Michael '87 Max

when i drive my car and it's warm up it sounds like a misfire but it not. The misfire happens only when i'm at a stop light and it's in drive. I have 87 with 130,000 miles on her so I change the spark plugs and the wires, new distributor cap and rotor, new coil pak. plug wires are spark plugs and the spark plugs are not cracked. spark plug gap is good because i checked them before i but them in so. I check the timming and set the timming at 20 degrees that what the manuel said to do. Found all vaccum lines that were crack and replace them. I work at a nissan dealer and ask techincian said that the fuel injectors are corroded and I was talking to my dad and he check about the injectors and said that he found a expert on nissans said how they were designed that the wouldn't cause a bump while driving. I don't kown what to do. Please Help Me. Thanks Mike

It sounds like a Fuel/air mixture problem. Have you had your emissions system checked??

What kind of plugs are you running? I get that with almost everything except NGKs. Also, did you put in that replacement/upgrade plate in the distributor. A little flier about the modification comes with factory distributor caps. Plus, are you running a Nissan dist. cap and rotor. Most aftermarket caps suck. Echlin from NAPA is a rare exception. Most don't fit right.

Yeah with your ignition, you should stay either OEM or NGK. People may say it just wires and spark plugs, but different brands have different specs, resistances, and so forth. Same goes for the distributor cap and rotor.
