Re: 1994 5.7 TBI Runs only at Hi-RPMs
jcat Thanks for the quick response. I agree not much to go on too. I have looked at all the hoses they are either plastic or rubber all look good No Cracks dried out etc..

I will look at the egr and post back. When cold the truck runs at hi rpms then down kicks when warmed up and then just stumbles and dies.

I'm working on the pressure for the fuel but feel it is not that as it starts and runs.
again No Check engine light and it does have an obd II not an obd I as it was manufactured in late 1994. Any other suggestions-?
