Engine Performance problem
1989 Ford Bronco V8 Four Wheel Drive Automatic N/A miles
302 fuel injected, custom installed 3" exhaust from the "Y" back, duals after the converter.
I blew my engine and the bronco sat for at least a year. It ran fine before it blew. I finally had a new jasper engine installed. From the day I got it back I felt like it didn't have the upper end power I felt it should have. As the months went by, It has gotten worst. Now it seems as the engine warms up it runs worst. To me it feels like it is running on 4-6 cylinders. I have a check engine light. The machanic that put the engine in and the dealer said it had to do with a lean mixture, egr code, O2 senser. Between the three of us, we changed the egr and 02 senser twice, didn't make a diff. Also chanced the temp. Sensor, map sensor, Tps, (can't recall the name) some other sensor on the air intake. The mechanic that put the engine in had the bronco for the past month trying to figure it out. He tried a new fuel regulator, fuel filter. Remover the injectors and had them sent out to be tested and cleaned.
Any and all help would be greatly appretiated, I have spent probably 800.00 on this problem and its not fixed.
Thank you in advance
P.S. Also tried a new computer
have the same problem?
