Wanted to get some input. Changed spark plugs 2 days ago and deleted the PRVR. Car ran fine for a couple of min but when i drove it to work yesterday it stalled every time I came to a stop and when I started the car. Fixed the problem by adjusting the idle screw but I was wondering if anyone has ever encountered this just from changing the spark plugs. Plugs are 7B. Running 615cc new style injectors and JWT Chip. Replaced all the connectors for fuel injectors/Idle control/Coils etc. PTU connections are good. Car runs fine now. Why would spark plugs change idle? Thanks in advance for any advice.
