325_driver 422 Report post Posted March 26, 2007 hey guys ive taken the bimmer off the road for a bit and its back ive got a 325i e30 not that it will assist. some of you guys might have had this problem. its now back on the road and when i put the foot to the floor, mainly in first it no longer smoothly accelerates. i can smoothly slowly accelerate but if im going 10 - 20 kmh in first gear and put the foot to the floor the car starts doing a major bunny hop you could say or if you try and do a burn out and drop the clutch it will get traction and then bunny hop. have a new fuel filter dont think its the fuel pump since no other gears have this effect dont know why it could be the spark plugs since their fairly new a mate of mine said it sounds like it could be the diff mounts or some thing ? any of you know what im talking bout or can assist ? any thing would be good thanks Quote Share this post Link to post Share on other sites
Gus 5 Report post Posted March 26, 2007 check the engine and gearbox mounts are fine...if your doing burnouts it really doesnt help them. if they arent, they are probably sending the fan into the radiator Quote Share this post Link to post Share on other sites
325_driver 422 Report post Posted March 26, 2007 i was only trying to light up the wheels trying to see what was up with the engine. a while ago i had a prang into a wall it cut the oil cooler in half and sent the radiator into the fan no major damage. could that be the problem when the car launches foward the fan goes in the the radiator slowing the crank down or some thing ? you got a number i could quickly ring you on ?

Andrew 30 Report post Posted March 27, 2007 So are we talking misfire here? Or does the engine work fine? Check ignition, fuel, AFM and report back. Quote Share this post Link to post Share on other sites

Your fan hitting the radiator doesn't affect the crank but does prevent proper cooling. If your engine/gbox/diff mounts are split then you'll want to replace those asap, not cool hitting 6000rpm and hearing and feeling strange stuff.

325_driver 422 Report post Posted March 28, 2007 ill try and explain exactly what it does and where the problem lies if its not in gear i can accelerate fine, no engine missfires, and engine temp is very normal if i launch the car foward at a low speed to quickly it will put its self into a major bunny hop so from second gear i can plant my foot no problems cause im going at a reasonable speed but there seems to be a problem launching the car foward? if that makes anymore sense?
