I have a 00 maxima v6 5 speed with 175k.. bought it 2 weeks ago having major issues! Car jerks jumps and hesitates when I pull out it feels like it's slamming around in the engine bay.. also lacks power under acceleration NO CEL! Also unplugged MAF car shuts right off all 3 front coils replaced with brand new no change... haven't done the backs yet but the car does not misfire so not thinking it's coil related..idles fine an revs fine in N and in any gear with the clutch pushed in... what else could be wrong?? Need help ASAP almost got hit by an 18 wheeler today because I tried to pull out onto the highway.
Any ideas???

Did you try another maf?

MAF sounds like a good possibility.

But on another note, when you say no cel, are you saying that the light is not on? Or have you checked for codes and there are none. If the cel light come on during the light bulb check, then you probably have no codes.

By no cell I mean that the car is throwing no codes, and I thought that if you unplug the maf an the car shuts down that meant the maf was still good?

Is the engine light FLASHING or BLINKING while driving? That could mean misfiring

And for OFF MAF = CAR SHUTS DOWN = MAF GOOD = WRONG

Read up on the FSM for proper MAF testing.

Knock Sensor.

They throw ghost codes when they are going out but the symptoms such as lack of power at complete random persist, its amplified in an manual car. Replace the sensor AND the harness, everything will return to normal afterwards. While your in there replace your plugs and fuel filter.

It threw a 1320 code.... cleared it hasn't came back, also if I only step on the gas 1/8th pedal it doesn't really jerk a lot only if first... then if I jump on it over 3k it lags studders an falls on its face.
