Hi guys picked up my car after a standard service also had them replaced spark plugs and leads when i picked it up it was running worse than before they used the correct plugs, leads, they cleaned the air intake and even a efi clean to get rid of the carbon crap So where should i now look for the problem Can i reset my ecu or something like that? PLEASE HELP!!!!

make sure leads went in the correct positions.

Apart from that mate, call the mechanic and tell them its now running like a bag of s**t. You paid for a service and if they have f**k up its their problem to find the error, not yours

Yeah ill be taking back tomorrow for sure just thought id ask incase it was something simple cheers guys
