Hi! I have a 95 intrepid 3.3L v6 with 233,000 km on it. I change my oil regularly and I have one problem. It started about 3 months ago. When i turn on the car when the engne is cool everything is working fine. When i start to move and engine heats up juss a lil, at my first stop sign, when i stop i hear the engine is "knocking" or "ticking". As Irev the engine juss a lil the ticking increases i.e faster, and the more i rev the faster it ticks. My first assumption was that fuel injector cleaning might be needed. There fore i bougt pennzoil fuel injector cleaner and haven’t applied it yet. My q is... Is it worth trying to clean the fuel injection system, or is there a known cause for this problem? All your answers are appriciated, Thanx.
