I have a 91 si hatch with a d15b8, when i turn on the car the rpm are at 2000 if i give it gas it revs nice but when i take it out to test drive it. It runs good at frist but then it start to die i try to give it more gas and nothing it just turns off and then i turn it back on it does the same thing agine start good and it turns off. What could it be ive already checked
- timing
- replaced fuel pump
- checked and cleaned tb

 

Has the car been running fine and this just started happening out of the blue?
A plugged exhaust (dead catalytic converter) will act like how you described.
Under load it just bogs out.
Try disconnecting the exhaust under the car at the cat.
You can take both bolts out, move the cat over, and just put one bolt through so it's wide open exhaust.
It will be a LOUD test drive, but will give you instant feedback telling you if that was the problem.

 

Ill try that thank ill post back to let u know..

 

No luck still doing the samething :/ before i had the d15 i had a Z6 that ran smooth and then i drop in some ebay 4-1header but after a week oso the Z6 starting acting up by turning off at stop lights and then one day it just broke down and wouldnt start no more. When i took it home the next day and start it up it was shotting all the oil from the exhaust, could it be those f@*ken headers..

 

Could it be the header - Umm, No.

What all did you transfer over from the previous engine?

Also - it could be a massive vacuum leak...

 

Its the dizzy... Check the rotor and the cap.

 

Problems with the distributor will make oil shoot out of the exhaust? This is amazing!

 

Oil coming from your exhaust = piston rings...

 

the d15b8 with d16a6/z6/y8/b7 manifold will choke.

 

Im running a Z6 manifold and yea it starts choking and its turn off way is that? help please..
