Rattling sound
Rattling sound Lately I've been noticing that if I'm in too high a gear, or not in the power band yet, when I give it gas and the engine sort of bogs down there is a rattling sound coming from the engine compartment. I don't hear it when the engine is in the power band and actually accelerating. It's only when the motor is bogging down. A friend suggested injector(s)? Any other ideas ... I really have no idea where to start.
I have the same problem. Kind of embarrassing. I got my dad to take off slow a few times with me standing outside but all I could tell was it was coming from under the hood. Maybe the exhaust rattling, cats? Hope someone has an answer.

hey jp......are you sure its not "pinging"....thats what my car used to do.....if you are under a load (in a high gear and hit the gas) and it makes that noise its "pinging"....i ran some octane booster through mine and some fuel injector cleaner and it helped for the time being.

haha yah i do the same thing too sometimes! Just keep your foot in it and keep the car above 3,000rpms constantly and you won't hear it at all! If you want to i can't take you for a ride in my car and you can listen to see if its the same thing. (mine still does it under a load). BTW....i didn't even realize i posted that up last night....lets just say i wasn't in my right state of mind last night

i had the same pinging issue and i to thought it was rattleing or sumthin loose it wound up being the gas station i was useing it was 93 octane but shitty station i tried octane booster injector cleaner they didnt hel even a little i switched to sunoco 93 and i havent heard it sense. they noise was when u were around 1600rpms down low and u would sorta blip the gas or just touch it to move and it would go cling cling clank and be gone again. also did it up high for me to but i didnt notice that right away
