typhoone Posted April 17, 2007 Share Posted April 17, 2007 okay, let me start by saying that I am used to driving a front-wheel drive car. I was going around a corner today, apparently much too fast, and I spun out. I didn't hit anything, and the only thing that got on the Z was some dirt, but I think something might have come loose or something because the Z is still driveable, but the acceleration isn't as quick when I floor it, the rpms build up much less quickly, there is a lot of backfire or something when I floor it and also when I let off. do you think I bent something or something came loose? the Z has always been loud sinceit doesn't have a muffler on it, but now it kind of sounds like a helicopter passing over head when going any speed. I know I shouldn't have been going fast around the curb, but I didn't realize there was THAT much of a difference in handling between fw and rw drive cars. I have done the same speed around the same curb in my eclipse plenty of times without a vibration....much less a 360.....I hope I didn't break anything. do you guys have any ideas? thanks in advance -Typhoone Quote Link to comment Share on other sites More sharing options...
typhoone Posted April 18, 2007 Author Share Posted April 18, 2007 do the symptoms at least sound like a vaccum leak? i am not sure because, even though it takes longer, it is still getting up to full boost. any ideas??? Quote Link to comment Share on other sites More sharing options...

mtcookson Posted April 18, 2007 Share Posted April 18, 2007 Backfiring usually means its running rich. I'd first do a quick check on the ECU codes to see if anything comes up. If nothing there, you might then check for some more boost leaks. If its a vacuum leak it'll have some idling issues, are there any? Quote Link to comment Share on other sites More sharing options...

typhoone Posted May 17, 2007 Author Share Posted May 17, 2007 it is amazing. i was terrified that i had a bent valve, or who knows what else. guess what i did to fix it. I gave it a tune up....really. i got new plugs, wires, distributor cap, etc....and no more backfire, no more loss of rpms....nothing...it is perfect. =-) i am VVVEEERRRYYY happy now.
