Make sure you MAF is plugged in GOOD!! Check IAC Motor Connection!!

Could be a bad MAF, fuel pump/delivery, coil pack or module.

Plugs and wires.

Since you have never seen the car perform normally it makes troubleshooting much more difficult.

Since you seem confident in your recent work I would suspect a defective part on the car.

i was trying agin black smoke at shift to 2nd
feels like it way too rich but im guessing

 

[Quick6'n'-K.C.]

black smoke is rich-

what plugs did you put in it?

got a boost gauge? does the boost drop and then the black smoke come out?

what computer chip is in the car? maybe that is why the headgasket went in the first place?

Have fuel pressure gauge? Possibly you need a new fuel pump. Could have caused HG failure in the first place. Check fuel filter.

Hello,

Isn't there a ground on the back of one of the heads?? is it good?

 

[Chris McDade]

It sounds like a fuel problem to me.

Since you bought the car with a blown head gasket I would do a compression test.

Good Luck
