Matt GTi 0 Posted December 16, 2003 When I sit with the car at idle, and rev the engine, I get a popping from the exhaust, is this just due to the mixture being incorrect? Quote Share this post Link to post Share on other sites

h100vw 0 Posted December 16, 2003 A weak mixture often causes popping on the over-run. A weak mixture burns slowly and is still going when the exhaust is open. Hence the popping. This should be almost erradicated on modern dubs as they have over-run fuel cutoff. The fuel is shut off, until the engine speed comes down to about 1500 revs and then it cuts back in.
