Hi guys, I need help.
I did an oil & filter change on the weekend. Everything went like normal, except I dripped some oil on the intake manifold side. Not much , would have been lucky to be 50ml. I decided to give the engine a degrease to clean the excess oil off. I did not spray degreaser or water onto any sensors. When I came to start & drive car later , it would not idle. It would run with a little throttle. Sometime the car will idle but very low 400rpm.
I have started a elimination process until I get it going. Things i've changed & tested.
I checked timing marks on crank & cams
I've check spark & while I was at it I changed the cas, igniter, coil pack. Spark is good.
I've check isc but most likely did not need to as I'm simulating idle from tps ( ecmlink V3 )
I unpluged tps to check for CEL ( got fault straight away. Reconnected & fault went away ( I also checked voltage with ecmlink. .59V @ 0% )
Fitted new spark plugs
When I had running I turned the injectors 1x1 to see if I notice a change in rpm. Rpm dropped with each injector switched off & on.
I'm running SD so I've ordered new GM 3 bar map to be safe. Should turn up tomorro. I"m still getting readings from MAP
I've checked fuel pressure
I've checked all fuses.
Car seems to drive ok. Oil pressure is the same as the before the oil change.
I'm totally lost.
Any advice or ideas would be great.
Thanks in advance guys
