ZeroK66 0 Posted February 14, 2004 Hello all, Noticed the last couple days the car seems to be popping a hell of a lot when I decelerate. As great as it is the first few mins, I am now starting to get concerned. I am running G60 management just by the way... hence asking here :) Quote Share this post Link to post Share on other sites
dubster82 0 Posted February 14, 2004 my car does it too, thats when you know its a good tank of optimax :D Quote Share this post Link to post Share on other sites
Henny 0 Posted February 15, 2004 popping = over fuelling... :? The extra fuel blows out through the exhaust and hits the hot manifold/ cat / exhaust and ignites = flames and pop... :wink: It may also be a sign of a dead lambda sensor, as these help the G60 management control the fuelling... :| IMHO it'd be worth putting an Air/fuel meter on it and seeing what's going on throughout the rev range, and possibly getting a custom rolling road setup done on the chip... It's what mine's getting once it's bedded in, and I've not done anything as fundamental as a 20Vt... Quote Share this post Link to post Share on other sites
dubster82 0 Posted February 15, 2004 and just to note, hearing popping doesnt actually mean you have flames belching from the zorst. cheers Quote Share this post Link to post Share on other sites

LowG 0 Posted February 15, 2004 mate check your timing, retarted or advanced timing sometimes causes this, otherwise you will destroy your exhaust due time Quote Share this post Link to post Share on other sites
ZeroK66 0 Posted February 15, 2004 Mmmm, well, I am thinking Lambda... dont suppose the G60 lambda is designed to sit virtually next to a glowing Turbo... so perhaps this has gone. I have replaced the cold start sensor and the car is running far better (I knew this was shot) but made no diff to the popping. Noticed though since the sensor was changed black smoke quite often when in traffic and running against compression when backing off - all linked though to the popping it would seem, so doubt it is the sensor. Sounds like it may well be the lambda. Any other thoughts welcome Oh, how the hell do I test the lamba sensor? Quote Share this post Link to post Share on other sites
ZeroK66 0 Posted February 15, 2004 Oh, and regarding timing - I have NO idea how advance/retard is controled on this car... it does not use a dizzy yet uses the G60 management. Has a pickup on the crank and a little box of tricks Jabba put together to generate the pulses for the coil packs. Quote Share this post Link to post Share on other sites
