Car: '95 Maxima, 5-Spd, 140k. New KS, Coolant Temp Sensor, Fuel Filter, recently cleaned TB + IACV. Still gets good gas mileage. No CEL. 93 Octane Fuel.


Under fairly hard acceleration, (only after the car's warmed up), I experience a noticeable, rhythmic series of power drops/surges as I pass through the 3000 to 4500 RPM range. It is certainly not a violent cut-out - it just feels like I'm lifting off the gas slightly about once every 1/2 second for as long as it takes to get through this RPM range. It commonly happens to me when in 3rd and I'm getting onto the highway.

This problem has persisted for nearly 8 months now - through winter and into summer - rain or shine. I'd previously gotten a Temp Sensor and Knock Sensor code, but I replaced both components. Other symptoms include a very infrequent but harsh power interruption that lasts less than 1/4 second and occurs below 2000 RPM when under medium/heavy throttle in a high gear. Additionally, the idle seems to dip somewhat every few seconds when stopped at a traffic light - but this is barely noticeable.

I've looked at a number of other threads pertaining to similar experiences, but the original poster typically does not include a final post summarizing the actual solution to the problem... ...so I can only narrow it down to one of the following:

MAF (incl MAF wiring)
Injectors
Coils
KS
TPS
EGR
SparkPlugs
FuelPump
Wiring/Grounds
O2's
One person even suggested that lubricating the throttle cable would clear this up (???)

Anyway - I'm left wondering if anyone out there has had this problem and could share a fix?

My end of the bargain: If you guys help me figure this out, I promise to post up the solution that finally works for me

Thanks a lot for the help!
