Well the truck has been in a shop a couple of blocks away for months now. I've be stopping by and started her up and driving her around. The day I took her into that shop It stalled so many times I had to have it towed in. Anyways, along way we've change a number of things.. Gas , fuel filter and gas tank, fuel pump, tbi intake gasket, added manifold sealer, had to change the distributor.

The truck starts up great every time and drives hard and fast for about a minute then dies. If I leave it idle, it does basically what's in that video (fluctuates) then dies.

The mechanic gave up on it .. he said that if it where his he would pull out the TBI and put in a 4 barrel Holley Carburator.

Thoughts about that? How simple to do the swap?

Question, can I put in a Holley Carburator and keep the Edelbrock intake manifold? The current TBI is an after market Holley currently. Details about exact parts in link on my signiture.

update: someone suggested i uplug the EGR to see if idle fluctuation would stop, and it does, but then never idles and seems to run way too rich. If this is true, any chance my TBI or the injectors themselves are still failing. BTW, when removed the gas tank the fuel did not look or smell like gasoline, it had a oily feel to it. I now have a fresh tank, fuel filter and super unleaded gas.. still stalls.

Thanks.
