No, very doubtful.
Could be the heat shield on the catalytic converter May be a bad bearing in one of the belt driven accesories i.e. Water pump Alternator Belt tensioner Idler pulley etc.
Yes, a missing catalytic converter can cause idling problems in a vehicle. The catalytic converter plays a crucial role in managing exhaust gases and maintaining optimal back pressure in the exhaust system. Without it, the engine may experience rough idling, fluctuations in RPM, and a decrease in overall performance due to improper exhaust flow and potential sensor issues. Additionally, the vehicle may trigger warning lights and fail emissions tests.
Could be an exhaust leak close to the engine or a bad catalytic converter. It also could be a bad mass airflow sensor.
loud rattling noise when idling.
A catalytic converter can get red hot on a Chrysler LHS primarily due to excessive heat generated from unburned fuel entering the exhaust system, often caused by engine misfires, a faulty fuel injector, or a malfunctioning ignition system. Additionally, a clogged or restricted exhaust can trap heat, causing the converter to overheat. Excessive idling or driving with a rich fuel mixture can also contribute to this condition. It's crucial to address these underlying issues promptly to prevent damage to the catalytic converter and the vehicle's engine.
I experienced poor acceleration in my '95 Chevy blazer, which eventually became so severe that when accelerating, the engine nearly stalled.It turned out that my catalytic converter was disintegrating, and choking off the exhaust so severely that the backpressure was causing engine retardation. I took the vehicle to a muffler shop, where they performed a backpressure test on the exhaust to diagnose the problem. After replacing the catalytic converter, the problem was corrected.
my first guess would be that it is your catalytic converter is plugged. Also,check the oxygen sensor. Also, the IAC (idle air control) may be at fault.
Yes, "sparkling plugs" is definitely detrimental to idling or smooth running of an engine
bad/partially blocked catalytic converter. - kind of a rotton egg smell, right?
Depends on which of the readings failed. Was it CO (carbon monoxide), HC (hydrocarbons), NOx (nitrous of oxides), or a combination of them?
Check your spark plugs and leads.
