It started at the end of a trip climbing a steep grade . It started missing and lost power. I took it in and was told #3 cyl. was missing . He recommended cleaning the injectors. He did with a pressurized can for about 15 minutes and while it was on the can it ran good . It did run better but started missing at an idle and anytime it is under load . Could this just be a bad injector or fuel pump ? I came from Oregon to Minnesota with the engine light on and it starts flashing while pulling a grade and missing it lost power only a few times
where it almost quit. Any help appreciated .
I had the exact same problem with a cylinder #1 misfire and did the turnup and change spark and nothing happened. I then had a side mechanic checked it with his computer and he got the same code, cylinder #1 misfire. He said the problem could be the ignition coil or fuel injector. He wanted $77 for an ignition coil plus $170 to install it so I told him I will do it later. Went on ebay and bought an ignition coil for $50 then have my friend boyfriend checked to coils for me. He didn't know how which was #1 so he tested the corner ones until he found cylinder #1 because he wasn't getting spark there. He replaced the igition coil on cylinder #1 with the one I bought and then reset the code. It's going on 3 weeks and I haven't seen that code came back. The car drives like new again with no problems.
Oh, the ignition coil is not hard to change you can do it yourself. The #3 coil is going to be at the top far right. Make sure you buy the right ignition coil for the right year and model.
