cardboard Posted June 17, 2003 Report Share Posted June 17, 2003 Hey, I got a 1990 Pontiac Grand Prix with 160,000KM (low, I guess) on it. Its having some problems lately though. I know a little bit about cars, but this just doesnt make sense. Ok.. The car is perfectly fine, when driven normally. But when I start to fool around (go above 3,500-4,000 RPM) the car starts makin this ticking sound at idle, which increases in speed as you go faster. It almost sounds like a damn DIESEL!!! Its LOUD, you can hear it well in the cabin with the window rolled down. But then after I leave the car off for a little and turn it back on, its back to normal. I dont think the performance decreases at all, although i cant tell because I cant remember how it ran before it started doing this. As far as I know, the ticking sound is coming from the engine. But the wierd thing is that the sound isn't constant, it only starts happening when I rev the car fairly high, and then it goes on until I turn off the car and wait a little while. Oh yeah, and recently I got the catalytic converter and the muffler changed, and this sound started to happen after this repair. I dont think it is related to it. But im not too sure. I personally think that something is messed with the car, but since it aint really mine (its my moms ) I dont want to make it seem like I did it. So that is why im trying to see if it is serious or not (I think it is :oops: ) Oh yeah , and it may be related to the time that I went 190KM/H in the car, it just doesnt seem the same since then. I feel like such a dumba$$ :oops: Does anyone know what could be wrong? I just dont get why the sound goes away and comes back :?: Its pretty wierd. Oh ya, and if no one knows what it is, Ill try my best to get a video clip with sound of the car running so you can hear how it sounds like. Thanks! Hopefully its only a minor problem, and I can get it fixed. (Sry for the long post , lol) Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 17, 2003 Report Share Posted June 17, 2003 I think it sounds like your fuel injectors going bad. They make a loud ticking when they are going bad Robby Quote Link to comment Share on other sites More sharing options...

Lifters. Werd. Check the oil level in the car. Quote Link to comment Share on other sites More sharing options...
