hey guys I have been dickin around with thie car for sometime now and still am coming up short on the problem, here is what it does.

It starts rough, then after about 10 seconds it will smooth out. Could this be somekind of default mode or something. after it has been runnin for awhile it backfires horribly so i kno its running rich.

here is what ive done so far
new plugs and wires, compression check came out good, all timing is perfect, cleaned EGR valve, air filter, checked injectors. It is still running like ****

I do have a MAP sensor code, could that be the cause of all this
please help asap

 

what's the code?

 

code 5 i believe.

and late bump cause computer was being retarded

 

change it and then repost
