Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
Does it act like there is a rpm limiter such as not wanting to go over 4000 rpm? Thanks.
If it acts like it hits a rpm limiter that is a common symptom of a clogged catalytic converter. You can completely remove front oxygen sensor from exhaust to relieve exhaust pressure. If it runs better with oxygen sensor removed you know the converter is clogged. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
How do you know it isn't' clogged? This symptom pretty much always means a clogged converter if it will not go over 4000 rpm.
The only other thing that comes to mind is a weak ignition coil but I'd still recommend removing oxygen sensor to see if it helps. If not, check to see if each coil jumps a 25kv gap.
