I'm thinking MAP(Manifold absolute pressure sensor) but a reliable mechanic should be able to scan your ECU and find out for sure.Good Luck.

I havue a 1998 ford escort sport When I first start it it blowing out white smoke It doesn't smoke anymore while driving My idling is high to 2000 rpms My car okay?


white smoke can be water in the exhaust if you park with the rear end facing up hill it will store water in the cat and take a few miles to clean out. 2000 rpms is a bit fast. should be around 800-900 rpms. it could be a sticking idle control. take it off and give it a good clean out.

1999 blazer only starts when primed and then wont start after sitting


Black smoke is usually extra fuel, but you say you are priming it to start so that could be why.
Have you checked fuel pump pressure before and after cranking ?

My 2004 ford 450 superduty deisal wont start in the mornings and when it cranks over black smoke comes out the tail pipe


If it finally starts after a lot of cranking, I'd have a look at the glow plugs. If they've not been changed since the truck was built, they've probably come to the end of their life.

1990 oldsmobile CC SL running very rough, smoking, backfiring


Well Mike" a few things to check could be Breather on fuel tank /fuel return to tank pipe/ as pump can pump high pressure and excess has to return to tank and it sounds like yours is overfueling./take air cleaner off and all pipes and check for any thing partly blocking air flow/also check any black hoses coming from the engine breathers/going to air in take/make sure all cylinders got good compression

Black exhaust smoke comes out of tail pipe, now it wont run how do I fix this and where do i start


Black smoke is a sign of too much fuel. First make sure the air filter is clean. Now note if the check engine light works, and if it stays on, get the codes read to get an idea of what error the computer has found. (A bad coolant sensor for the computer can make the computer think that it's well below freezing and increase fuel) Try these as a start.
