I love my car. My check engine light has been on for about a month and I have not investigated it.

Day before Thanksgiving put gas in car and after a few miles remember it appeared a bit "sluggish". Sat idle for 4 days over Holiday. Drove about 30 miles (some City, some Highway) on Wednesday after short trips to work and back Monday and Tuesday where I did not notice anything.

Wednesday, I noted almost immediately it took more RPM's (6000) than usual 2-3000 for car to downshift. I also noted car struggling to maintain Freeway speed. As I would press accelerator down more, heard backfire from exhaust "popping" every 30 seconds or so. In Park I would rev engine and exhaust would sound like popcorn maker, but as I would take foot off accelerator, idle would struggle to keep motor running. Also surprised to see speedometer did not seem accurate as when I thought I was going about 60 mph, needle was over 80 mph and I was being passed by several cars. Pressing accelerator recieved a slow response which is not normal. Even on side streets where I know I was not traveling much over 20 mph, speedometer showed 40 mph. When I had foot on brake at stop lights, idle would cause whole vehicle to shudder increasingly more and more violent.

My knee jerk reaction is power/plugs issue and note I have not had plugs changed in about 10 years. After 15 minutes of this I dropped it off at a mechanic I have never used before near my work office at Noon. They told me they would get to it by 2pm, were open until 7 pm and call me with what they discovered.

They did not call until 11 am next day and said they could not find anything wrong with it. I suggested plugs, restricted air flow or pressure, or "bad gas". He said they did not think it was any of those things, stating "the obvious things are not jumping out". Asked my permission to go further in their investigation. I told him to put 4 hours of mechanic time to it, if they could not figure it out by then, to call me and we will proceed from there. He said they would call me at 5 pm with results.

No call, I stopped over there on Friday at 2 pm and front desk person did not know anything about a Honda being there. Asked in back, and techician came out and said he was getting bad readings from his computer. Said third and fourth cylinder would not register, but earlier third would intermittently. He suggested the computer for my Honda is malfunctioning on it and is a repair they can not perform, if that is in fact the problem.

Any help?

Hi sanskritsquirel,

Thank you for the donation.

You mentoned the CEL was showing, can you please let me know the error code? You can count the flashes on the ECU ( located under the front seats, either right or left depending on model ) with ignition switch turned to ON. The flashes would pause, meaning it is going for the next code, if any, if not, it would recycle the fault code.

When the 3 rd and 4 the cylinder is misfiring, was it due to fuel injector, spark or compression fault? If the injectors are not working, then it could be a failing ECU or contaminated wire connectors.

Speedometer is cable driven so I am not able to link it to any engine performance faults.

Well, it turns out my computer is shorted out under the drivers seat. I let my car sit for three months and used a company truck while I was out of town.

Water got in somehow, collected on the floor and shorted computer such that there is section of motherboard fused together.

I was quoted $800+ for a new computer. Are there reliable used computers? My mechanic has exhausted his contacts.

Hi sanskritsquirel,

It would not be easy to get the parts form scrap yards as the vehicle model is almost absolete.

You can try googling for the parts. Someone just told me he got one for a newer model online so they might have a used one for your model as well. Make sure you get the part number correct, different P/N might not work.
