2005 Jeep Grand Cherokee V6 3.7 L. HESITATING
2005 Jeep Grand Cherokee V6 3.7 L.
Iíve tried everything I can think of to fix a Hesitation / Surging problem. The car starts perfectly fine. It idles perfectly fine, but when I try to accelerate from a stop position there is no power at all, then a few seconds later I feel the engine actually engaging and the car takes off. During normal or fast driving the car pulses and I can actually see the RPMs slightly shifting up and down. It feels like is shifting between a few cylinders to all 6 cylinders, this is the best I can describe it. I have done the fallowing: New Spark plugs, New Ignition Coils, New TPS Sensor, New Oxygen Sensors, I have checked and cleaned all the vacuum lines, I have used air intake cleaner plus added Sea Foam to all the lines and the gas tank.
The only two other things that I can think of are the EVAP Solenoid and the EGR Valve. After that I have no more Ideas.
Any suggestions are welcomed!!!
