99 4cyl accord hard start short trips
I have a 99 accord 4cyl with 155k The car runs great steady idle no stalling but after short 5 - 10 minute trips is hard to start wait 1 hour starts perfect i have put several cans of fuel injector cleaner runs better but same problem put a used ebay main relay runs exactly the same plugs wires / cap changed 20k miles ago throttle body cleaned recently no engine codes I am leaning toward the coolant temperature sensor under the distributor but I hate to just keep guessing and throwing money at the problem. MY guess is that the computer is getting a cold engine reading from the bad sensor and too rich mixture. Any thing that I should check / clean before I throw more money at this thanks |

Check the ignition coil. It is known for failing only after
warmup for some time until it is completely dead.

I did not OHM test it yet. I bought a used distributor on Ebay $45 and am now back on the road. One thing I learned the hard way is that do not use the distributor bolts to muscle in the distributor or you will / may break the tabs like I did. Luckily I just swaped the good parts into my old housing. I discovered that if you turn the distributor rotor 180% it slides in nice so no need to muscle it in to fit. 2nd tip if you are unsure of spark plug wiring go to ebay either for sale cars or engines that fit your car and look for the best pic of your engine. I found this much easier to understand than the clilton book |
