The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM. The engine can stall at high speed, at low speed, or even at idle. A faulty throttle position sensor will not let your car accelerate normally. Though this doesn’t happen all the time.

What does it mean when your car lunges forward?

Lunges, to me would mean that it jumps forward. Because I am cognizant and sensitive to the problem, I am careful about not trying to press down (too hard) on the accelerator. I believer everytime that the “lurching” occurred, I was driving at a steady speed and not even expecting anything,…then it happens.

This hesitation could be potentially dangerous in situations like entering and exiting the highway from an off-ramp, where acceleration may be necessary to merge with traffic.

What causes a car engine to hesitate and hesitate?

Another common cause are dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire).

I have a feeling my problems are caused by my exhaust (burning a little oil, muffler is 5 years/60,000 miles old, God knows how plugged my cat is). Basically, the problem could be caused by anything. I’ll get started on my list in the next couple weeks and keep checking in for more ideas.

Why is my GMC Jimmy transmission so slow?

When it is cold outside, the transmission shift hard from 1-2 and takes quite awhile (as well as a low speed) to shift from 2-3-4. The RPM needle shakes violently back and forth thus preventing the vehicle to obtain speed. The vehicle WILL shift eventually, but this make going up a slight hill very slow and time consuming.
