1G Sputters/Stumbles under boost

[markdr7]

My 93 talon is having issues when I get into boost it starts to hesitate and stumble. If I keep on the boost, it will sometimes snap out of it and keep going. The car also has a very minor intermitent miss on idle. I did a boost leak test and I found out that the o-rings on the turbo were bad. I rebuilt the turbo and it still is having the same symptoms. Anyone else have an idea that I should try? By the.way the cars stock except for a 3" exhaust.

after rebuilding the yurbo did you do another blt? Chances are you'll have another leak. I played the find fix then find another for a few weeks.

Bad plug wires will cause this. I've had it happen.

I did do another one and I didn't find an more leaks. That was my first guess also, but it turned up nothing.

I was thinking plugs and wires. I just wasn't to sure if it would have those symptoms. I guess I could give it a try though. It can't hurt.

It can be a number of things!
You could be getting insane amounts of knock and its pulling the timing!
You could be running too rich, or too lean.
Timing may be off!
Plugs and wires may be bad!

how much boost are you running?
And what are upgrades to you have?
I see you have a ported 14b and a MBC but nothing else to support high boost!

That a different car. The one in question I just recently purchased. It is stock except a 3" exhaust.

well still, same goes for that car as well!
Can you give us some back ground on it?
Any thing recently done to it? Tuning, Fuel, anything?
