I give up...

EpilepticPuppy · 09-02-2007, 05:56 PM

I did a rebuild because I thought I had a bhg....while the head was off it was machined and milled at a engine shop. Put the thing back together, timing was done by a mechanic, and I have cleared out all the errors.

The problem is that when it starts it dies right away unless I give it gas. Then it won't stay started unless I keep it above 2k rpms. Is there anyway I could have put something back together wrong to make this anomaly not stay idle but still run at higher rpm?

I have changed the fuel filter. There is fuel pressure because I cracked open a bolt to see if it was torqued right, and it was.
I checked the vacuum hoses and they are all routed correctly.
I have tried kicking the tires.
I have tried talking nice to it.

But nothing seems to be helping.....Anyone have any suggestions before I take it to the dealer and give them a bag of money? If anyone guesses the problem correctly I will buy them a steak dinner, no joke.

It's an 89 NA supra exterior white with blue interior if that helps.

Theres a idle control screw in/on the throttle body, check that to see if its there. Its on the opposite side of the oil breather lines facing the front of the car.

Fuel filter.

I thought about that after i posted and then thought fuel filter.

Yes. It wouldn't fire up if you weren't getting any gas.

My 91 has 2 filters.
One is in the tank and the other is under the body up under the rear seats.

I had a similair problem, my motor would sputter when started up and would die unless I kept it above 1700 RPMs... Check to make sure your vacuum lines aren't cracked and are routed correctly. I had two go to the wrong place, switched them around, and now she purrs at a good 700 RPMs, nice and strong.
