So you may know I have an 18 year-old Honda Accord named Betty. I take a little pride since the car is so old that it no longer requires emissions tests. Anyway, Tuesday morning Erika had some trouble driving the car to work. It gave her a hard time starting, and then it died about a half mile from our house. Luckily, she was able to coast it down into a parking space at a nearby shopping center. But it wasn't moving. I came out to take a look at it, since I'm pretty much always able to get it to start. I couldn't. Luckily we have another (younger) car.
So Betty sat in the parking lot until lunch time, when I could get away from work and have AAA tow her to a repair shop. The mostly-friendly AAA lady on the phone suggested I have it towed to an AAA repair shop which was also close to our house. This sounded fine to me, so I followed the tow driver out there and gave the repair shop my information and car key. A few hours later I got a call from them. Guess what... They were basically afraid to work on the car since it's so old. I can somewhat appreciate this, since with an older car like mine a seemingly simple repair might reveal or cause other subsequent problems. The repair guy on the phone said I didn't owe them any money, and I could pick up my keys whenever I liked.
After work, I went back down there and talked with the repair shop guy a bit. They suspect that my fuel filter is the original one from 1989 and these really ought to be changed every 30K miles. He hypothesized that this old (and likely very-clogged) fuel filter was restricting the flow of gas so much that the engine was starving. He further projected that if I was to replace this fuel filter, the components past it along the fuel system might fail due to the sudden increase in pressure.
So I was stuck between a possible cause to the problem and the concern that I could cause more problems by trying to fix it. The mechanic said the car would start sometimes, but it took several tries. I didn't have any luck, and I thought I'd probably run the battery down. So they said I could leave the car in their lot overnight and have it towed elsewhere tomorrow. I was tired and I decided to head home.
Thinking about the problem at home, I got out my car repair manuals. I bought these back when I bought the car, since it didn't come with an owner's manual. Back then I thought I'd get more useful information from a repair manual instead, and they were cheaper. The manual detailed how to change the fuel filter, and it didn't look difficult at all. I thought it should be worth spending $30 or less to replace it myself, and at worst I'd still have a car that doesn't run. So I ran by Advance auto parts and picked up a filter for $16. I gathered up all the tools I might need and went back down to the repair shop to do some after-hours repair work. I thought it was pretty funny to be doing this sort of thing by myself while I was right outside the repair shop.
While working, I talked on the phone with Matt, a friend who knows more about cars than I ever will, and he suggested I try to change the filter. He didn't really buy the mechanic's story about a new fuel filter causing problems. He also said if I still had trouble after that, I should give him another call and he could take a look at the car for me. So inspired by this, I finished replacing the fuel filter by the street light over the parking lot. One of the banjo bolts (yes that’s a type of bolt) was on so tight, I had to use an oil filter wrench to hold the old fuel filter in place while I used an adjustable wrench on the bolt.
Then I crossed my fingers and cranked the engine. No good. I realized this new fuel filter was bone-dry and I may have to try a few times to work the air out of the line. So I did, and on the third attempt the car sluggishly started. Hooray! I called Erika and asked her to put down the new Harry Potter book for a few minutes to help me drive the other car home. Unfortunately, my conclusion of success was premature.
I had driven the car to the edge of the shopping center and gave it some gas to make my way onto the street. The engine immediately died. I coasted backward out of traffic and gave Erika another call to hold on a while. I thought maybe there was still some air in the line and I should just drive it around the parking lot a bit more. So I tried. The car repeated its problem.
After 30-45 minutes of examining the problem in detail and a couple calls from Erika, I came to these conclusions: The car would usually start sluggishly. It would idle all day without any problems in park or neutral and I could even rev up the engine a bit and it'd be fine. When I shifted to drive or reverse with my foot on the brake, the engine would idle poorly. The rpm would drop way down but usually come back up. Sometimes it would just die. If I gave the car any gas in drive or reverse, it was likely to die. I could allow the car to putt along in drive most of the time if my foot was off the accelerator. Reverse was worse than drive. If the car was pointed downhill, it seemed to do a little better. Uphill was rough. So I eked the car into a (different) parking space and called it a night.
At work, another friend (Jeff) suggested the transmission might be the culprit, since the additional tax of trying to turn the axle seemed to make the engine die. I hoped this wasn't the problem, but Jeff also warned that there may have been some merit to the AAA mechanic's concern about the car being so old. I shrugged it off and belayed my fears of Betty coming to the end of her road in a shopping center parking lot.
After work, I called Matt back and left him a message about my predicament. Erika, having finished the new HP book, was eager to take a look at my car too, so we both headed that way after work. No changes, but the car was a little more trouble to start. I think it was harder with a cold engine. While we were there, Matt called back and said he'd be happy to stop by in a few minutes to take a look, since he was on his way to go running. So while waiting, I somehow got a free drink from Hardees, since the cashier was feeling nice and they were short-handed. Matt came by and gave a five-minute assessment of the situation. I explained my findings from the previous night and gave him a summarized maintenance and repair history of the car.
In about a minute and a half, Matt had the distributor cap taken off and found the most likely problem. The rotor button's metal contact plate had all but worn away in the center. This would need to be replaced. He took a look at the spark plugs and suggested they were due to be replaced too. Matt said the ignition wires might be getting old, and they were a third possible problem. A distant fourth possibility was a part called the vacuum advance which affects the engine's timing. An even more distant possibility was the timing belt, which may have lost a tooth. Matt suggested I buy a new set of spark plugs and distributor rotor button. He even offered to help us put those in after his run.
So we ran out to Advance auto parts again and picked up the needed parts for about $10. After changing clothes, Erika and I returned to see Betty and we changed out the plugs. Just after that, Matt called to say he'd be there in a minute. He helped us install the rotor button, and I cranked the engine. Success! A silly $3 plastic part about the size of my thumb was all that needed to be replaced. It was probably a good idea to change the fuel filter and spark plugs anyway. But I was amazed. I have no idea how much a repair shop would have charged to diagnose the problem. We offered Matt our eternal thanks and shook greasy hands.
I can gather several morals from the story: Keep your car up to date in maintenance. Don't always take the first repair shop's opinion. And if you can, make friends with a former mechanic. Thanks Matt, the next round's on me.
