Hey everyone,
First of all, sorry for the cross posting but I believe it's relevant in all groups posted to. I have a 91 nissan maxima GXE with 190k, V6,
5sp. This car has driven great until 2 days ago. All of a sudden (literally overnight)it developed a miss that is noticeable throughout the entire RPM range. Car ran great Friday and then Saturday when I started it, the miss was noticeable. The idle is down to about 600 vs 800 it was before and power is down. I checked the plugs, wires, cap and rotor and they all look good. They are about 2 years old with roughly 15k on them. The miss seems worse when the engine is cold. I can't see any wires arcing and have verified that there is spark at every wire using a timing light. The check engine light is not lit. The car shakes mildly at idle and has kind of a pfft pfft sound at the exhaust pipe. Anyone have any ideas on what else to check? I am at a loss and need to get her running right again asap.Thanks in advance
Derek
