seanl82 23 Posted March 22, 2012 Red-x making it worse is probably just coincidence. Start off with the cheap and easy stuff. Replace ECU and fuel pump relays, and go from there. :D Quote Share this post Link to post Share on other sites
j77all 0 Posted March 23, 2012 thankyou would you know what numbers these relays are please Quote Share this post Link to post Share on other sites
seanl82 23 Posted March 23, 2012 Ecu relay is 30 iirc, fuel pump will be either 67,80, or 167 dependant on time of manufacture. :smug: Quote Share this post Link to post Share on other sites
sexybourbon 0 Posted March 23, 2012 S exactly like what mine used to do ! If it hapens again as bad as it sounds next time it happens start the car and put ypur foot flat to the floor and rev til it tiks over by its self . My old valver used to do this ever once in a while and i could never find out what it was , when i sold it i spoke to the new owner and it turned out it was a knackers cold start valve so maybe this is your problem Quote Share this post Link to post Share on other sites
dubweiser 0 Posted March 25, 2012 Had similar problems with mine a few year back and it was the lambda sensor Quote Share this post Link to post Share on other sites
