Hello to all.
I have a question regarding a 1999 Maxima. Idles really smooth. Step on the pedal and there is a notieable stumble. On the highway rides like a champ. Tach needle seems to jump around a bit at idle. A little high also. (about 1200 then drops to normal).
Any ideas. I have been told it could be the MAF or the TPS.
Any and all help is appreciated!
Blessings to all

... Idles really smooth. .... Tach needle seems to jump around a bit at idle. ...
Can be MAF or TPS or bad connections. See link below... TPS only when cold (first few minutes)
Mileage? Coilpacks die by the mile, only replacement helps.
Read self diag results.
Idle is what? Smooth or jumpy? Cold/warm?
