1999 Honda Prelude Stalling

Not very detail, but I will try to answer your question.

First, check with the dealer if your car is one of the many under the recall of the ignition related components, you will need your VIN #. Second, check your oil level, preludes tends to burn alot of oil. Rattling noise, hmm, while the car is running, Rev or tap the accelerator from idle to 1500 rpm quickly to hear any rattles, maybe heat shields or broken brackets from the exhuast systems. Could it also be Oil burning smells from recent oil change spills from the oil filter area onto the flex exhaust piping. Good LUck
