franchise 1 Posted October 18, 2006 Report Share Posted October 18, 2006 Does it sound weird and pop as though it is at the front right but in the exhaust at the same time? Especially when you accelerate from stand still? mine did that when my tb and maf plug were fuuuuuuuuuuuuucked. If your maf plug and wires are all taped up undo the lot and check the wiring, mine were done by a blind kid with no electrical nonce. Re-solder, re-tape and away you go.

matth76 1 Posted October 18, 2006 Report Share Posted October 18, 2006 Cams can make a car pop a bit in the exhaust esp when you go down to a low gear or let your foot off the throttle...but that is overlap leading to unburnt fuel. You shouldn't lose power though and the popping is only slight. Sounds like you have something else going on. Do you have any other mods? Def sounds like you unburnt fuel for some reason. If you're near Stealth they should check your car on their rolling road and sort your prob out straight away. Link to post Share on other sites
