Casual - Justin Foell

In 2011 my family and I took a vacation to Three Lakes, Wisconsin (near Rhinelander). While I was there I was able to take my new mountain bike out for a spin at the Anvil Trails.

Just before Christmas in 2016 my 2002 WRX didn’t want to start. It was the day after the coldest day of that winter, and that apparently took its toll.

I initially thought it was my fuel pump because normally when I turn the key to “on” before starting, I can hear the pump prime. After getting it towed home, I realized my series 1 AEM Engine Management System had died. I couldn’t get it to connect to my computer to do any sort of troubleshooting. After going to AEM’s website, I learned that support for the series 1 EMS ended on December 31st, 2014 – two years earlier.

So back in went the stock Subaru engine control module (ECM), and I was back on the road but with my check engine light on. I knew the light would come on because I had removed the factory narrow-band O2 sensors and replaced them with an AEM Wideband unit that provided the AEM EMS (and the driver) with more accurate air/fuel ratio information.

Also, I had installed a different boost control solenoid valve. Since this was an AEM option the stock ECM wouldn’t recognize, I simply unplugged it and let the turbo wastegate be regulated mechanically. It would only allow for half the boost of normal, but I was OK with that since I just needed to get it to drive through the winter.

Then one day after work it had a rough idle with some low RPM hesitation. It drove fine that morning, so I suspected something electronic had failed.

Dealer Visit 1

I brought it to the subaru dealer thinking they could give me some better clues, but without the stock O2 sensors installed, the check-engine light codes would only indicate that problem.

What bothered me about that first visit was the service manager repeated everything back to me that I told him when I dropped it off (thanks!?). I felt they were relying only on their Subaru scan tool results and not their years of expertise. The service manager tried to tell me that without the boost control solenoid my car would run unlimited boost! I remarked that without the sensor it’s a mechanically regulated system that would only allow half the normal boost pressure. Did he not understand how a turbocharger wastegate works?!? He then remarked that I seemed to know more about what’s going on with the vehicle than he did.

Oy – I brought it to the Subaru for their expertise. I could have taken the car to Midas and received the same response.

So I took it home and reinstalled the factory O2 sensors and boost control solenoid. As I suspected the problem wouldn’t go away, but at least now the check engine trouble-codes were more accurate. Misfires on cylinders 3 & 4. Not particularly helpful, but at least more correct in assessment.

Dealer Visit 2

At the dealer, they were convinced the misfire had something to do with the valvetrain. Could be carbon deposits, a burned valve, a valve guide, etc.

In total I spent $400 for them to tell me

You need to plug your stock O2 sensors in.
You need to plug your boost control solenoid in.
You might have carbon on your valves (or worse), preventing them from closing fully.

Also they sold me some “top engine cleaner” that looks to be SeaFoam in a Subaru branded bottle.

I’m not saying $400 was an unfair price for the diagnosis. I was glad to pay the money to find out what was really wrong. I was more upset that I felt they were relying on their computer scanner more than their actual experience.

Air, Fuel, or Spark?

So I took the car home and started doing the diagnosis myself. The factory service manual suggested troubleshooting rough idle by checking fuel pressure and intake manifold vacuum. Fuel pressure good, vacuum seemed a little jumpy.

One of the possible reason for the jumpy vacuum was valvetrain problems, but there were others. Before tearing into the engine, I still felt some electronics were at fault.

The way it drove, the idle was very rough, but occasionally once the motor reached 2-3k RPMs under load, it would “kick-in” and surge back to life.

With fuel good and air within range (just jumpy), it was time to investigate spark. Years ago I had replaced an ignition coil pack. I don’t remember the rough running being this bad, but I thought it was worth a shot. On a whim, I ordered not one, but two ignition coil packs for cylinders 3 & 4.

Voila! $180 later the car was running as it had for years. No need to rebuild the valve train. Just enjoy the ride. Sometimes you need to trust your gut (and the feeling through your butt), to get the full picture, and not just blindly listen to the computer.

← Summary Only

Normally I write about these rides before they happen, but this year we went old school. We printed over 1,000 of the flyer above and distributed them through Fridley’s elementary schools. I was excited to see it on the front of the take-home packet when my son brought it home.

Milk crates were surely one of the first accessories ever strapped to a bicycle. It’s the simplest way to add significant carrying capacity to any bike. One of the first things I did when I got my bike was add a rack and a milk crate – but I wasn’t quite smart about it.

I wanted the crate to be removable, so rather than securing it with zip ties, I recycled some old tire tubes and inter-wove them with the rack and the holes in the crate. It seemed pretty solid, so I thought I’d make a trip to the liquor store. The problem with the tubes is they’re made of rubber, so they stretch. They stretch a little too much for a beer-laden milk crate.

When I got out of the saddle, rocking the bike ever so slightly was enough to stretch the tubes, and send my beers flying. I burst some Surly’s halfway home. Lesson learned.

Touring a city by bicycle is the best way to get to know it. You can move quickly from place to place, and stop easily along the way. You’re never too isolated from your surroundings to enjoy any sights or smells along the way.

I’ve made it a point to book a bicycle tour in new cities I’ve visited, and you’d probably be surprised which ones were the best. That is not to say I’ve ever had a bad bicycle tour experience, but some are just better than others.

1. Brussels, Belgium

This bike tour is my favorite for a number of reasons. I was able to share the experience with my then 10-month old son Jules. Even though he doesn’t remember it, he was a great passenger. We were also able to eat what I can only describe as life changing french fries during the tour.

Our tour guide spoke perfect english – because she was from Ohio. She was none-the-less very knowledgable about Brussels and its amenities. We stopped by several landmarks including the European Committee of the Regions (where the European Union meets), mannequin pis, and several monuments.

But the best stop was at a market in Leopold Park that had a permanent french fry stand called Maison Antonie. The fries were cooked in lard which was so clear it simply looked like boiling water. They had at least 20 different sauces – ketchups, mustards, hot sauces, barbecue and several variations or each.

2. Toronto

The Toronto bike tour was great because of the diverse neighborhoods. Each of them seemed to have a specialty cuisine whether it was a bagel shop or a sushi shop. Our tour guide was very knowledgable, and she offered her favorites for each neighborhood.

3. Portland

I put Portland last on the list not because it wasn’t great. It was a very good tour. But perhaps with Portland being the cycling mecca of the United States, I had set expectations too high.

It was a good tour, and I’d easily recommend it to anyone visiting. Our tour-guide was very knowledgeable and knew the city inside and out. They even gave us maps with a few of their favorite spots highlighted.

I wished we had made a quick stop along the tour for a beer or some french fries. Maybe in Portland’s case it should have been a donut instead – our guide suggested Blue Star Donuts over the more touristy Voodoo Donuts. It’s all probably my mistake because I didn’t instead sign up for the beer or foodie tour.

But maybe it is just Portland itself. Fun, but predictable. Even being naughty here is legal. Kind of homogeneous. Maybe it’s just me.
