Unhappy Help!!!

1990 Bronco Full Size Eddie Bauer 4x4 351w. My engine is running good but every 3 or 4th time my engine starts stuggling and then finally dies at the stop light. I will start back up and run but it can't be good on the truck. No engine warning lite however, I have been told that the engine has blow by and is worn out, I can physically see smoke *(when oil cap off after warm) however not really eating oil.

I've had timing set, rotor, cap plugs and pwires, oil changed religiously with high mileage oil.

it appears to me that maybe the fuel pump is giving out. It acts like its having trouble getting gas at Idle speed and dies however, when I get the engine speed up it run like a champ as long as I dont stop. Suggestions for a despirate man.

Thank you!!!

I would try replacing the fuel filter if you haven't done that in a while. They only cost like $10.

Fuel Filter done already

Sorry, the fuel filer has been changed. The air filter although blow by have to change it regularly.

Any other suggestions? I'm already looking at the TFI and the Fuel Pump as possible problems.

Fuel pressure regulator, perhaps.
