I have a 91 maxima, low miles considering the age (about 110). One day it just started running very rough, like a cylinder wasn't firing. I don't know enough to diagnose it though. Mechanic said one piston wasn't firing due to clogged fuel injector. Naturally, it's like a million dollars to replace it. I tried some fuel injector cleaner off the shelf (several times), but it hasn't worked. The car isn't worth but $1200 so I don't want to spend much to get it running smoothly - any ideas? I've also changed the wires and plugs but no change. Thanks!
have the same problem?
