Solution for stumble/hesitation at accel/low rpm.....

[CANHEMI]

Ok, So after months of diagnostics....and changing plugs (twice), O2 sensors, 3 EGR valves, 1 PCV, throttle body clean, 1 coil....the dealer was able to find the reason for the hesitation at low acceleration, typically at 2200 rpm. The car would give a feel of missfire, stumble........THE REASON WAS THE GAS PEDAL. The voltage sender on the gas pedal was not sending the correct voltage (or resistance) to the unit in the trunk (receiver unit).

Have your dealer check that before you spend any money......and change the pedal assembly.OOuuuuuuuuuuuf finally resolved.

i have taht same problem, did your engine light ever come on? mine was coming on and off for a while, but it has been on for the last full day

[CANHEMI]

It has been a few days...and all is well. So I am sure that was the problem.

Bruce, my check engine did not come on.

If you have a check engine, then the CPU has noticed a fault...they should be able to pin point what it is.

The had a check engine on the car before but it totally died and it ended up being broken valve springs for cyl 7&8. big mess too.
