I went to get my car smogged today after doing a tune up but they said it was misfiring so they aborted the smog. What should I look into to fix this? It is running so much better then when I asked my first question, so I am baffled as to why the misfire!!!
OK now you’ve given it a service you have to give it a tune to go with the service. You need to check your timing, and correct it if need be, and maybe check your valve clearance and adjust if necessary. Let me know what engine you have either the 4 cyl or the V6 and I’ll put up the corresponding engine repair manual for you. Here is the engine repair section. Document:
