Cyl contribution test shows #3 & #8 bad?
had a cyl contribution test done last wk before they did my cps it recall it showed cyl 3 bad i ordered 2 reman injectors just to have a spare had the test done again yest before i changed #3 and it showed that 3 & 8 were bad. i have been told a bad cps will cause this but just had recall done last wk. I have also been told 8 will show up falsely sometimes. My truck is an early 99 everything i have read says all 8 injectors are same is this true? and should i replace just 3 or 3 & 8?
