uhh well. Im stumped i dont know. I have a 87 Iroc z 305 with tuned port injection

Ive had it in the garage. tryin to figure out whats wrong.

It starts. but wants to die. I rev it to keep it alive but if you hold it it backfires so you gotta keep reving.

I had my friend time it he says he timed it perfect. I replaced Distributor cap, distributor and the rotor.

Im stumped idk. any ideas?

Ive recently put in a new battery and starter.

 

check for codes?

 

Well surprisingly the check engine light is not on. so i cant test that.

Hmm.

Anyway, are you sure it's TPI? You've apparently replaced some parts it shouldn't even have to begin with.

 

I replied to that thread. I will fix the double and post in here too.
Is there a reason you replaced the entire dizzy?
I saw that too saint ebony..... I guess we will see huh?

 

well i replaced the battery and starter because the starter was out and the battery had bad cells way before this problem happened.

To solve this problem, i timed it. Replaced the rotor, Distributor, distributor cap.

I gotta check injectors, vaccums, like the EGR valve

 

How many miles dose the motor have

 

130,000.

and im pretty sure it is a vaccum leak or broken hose.
so im doing that now and ill let you know how it went.
