99 Jeep sports diesel, jumps and jerks intermittently while driving. None of the gauges react but it is quite a ****, what could be the cause? Has happened science engine was replaced.
An automobile's ignition system may work fine while idling but fail during acceleration. Problem areas to be inspected include the spark plugs, spark plug wires and vacuum hoses. Car owners should look for spark plugs that are covered in oil or sediment or damaged, spark plug wires that have damaged insulation, and vacuum hoses that are unplugged or leaking. Fuel Problems
While most acceleration problems are likely caused by problems with the plugs, wires or fuel, a variety of sensors and other components can cause similar problems. a bad tps ( throttle position sensor ) will cause causes transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on takeoff, and surging while going down highway.
good-day ! check and or clean maf sensor if need be. you can by the maf sensor cleaner at most auto parts stores.
SOURCE: my car is jerking while accelerating and reaching certain RPM
I would look for a fault in the ignition system such as a cracked spark plug. Might need a scope check to put your finger on the problem
SOURCE: '99 VW Beetle just recently started jerking...
check ball joint strut mount when you jack up the car you shouldnt be able to lift tire if you can strut mounts are bad and check control arm bushings rear ones on front arms are usually coming apart
SOURCE: temp gauge fluctuates, fan comes on, car jumps in
there is air in the system
Testimonial: "Will give this a try and certainly hope this helps. Thank you"
SOURCE: Check engine light intermittently flashing, car jerking.
If you have one of the chain auto parts stores near you, check with them by phone first but most of them offer a free scan of your computer which probably has diagnostic codes stored related to your problem.
