first off i would like to say hello as a newbe. I just purchased a 1995 altima that has some issues.
to start off, it has an erratic check engine light. this problem seems to be throttle dependent which would lead me to think its a MAF problem(let of the gas and its gone, step on it and its back). when hooked a snap-on scanner up it listed problems with the air intake temp sensor, primary ignition signal fault, and the secondary o2 was sticking on its readings. i replaced the second o2 and the problem is still there. all readings from the distributor/coil and AIT are within specs. if i clear the codes it still has the problem with no codes. i have cleaned off the grounds. the CEL is not allways there. im kinda lost right now so any help would be great
