My friend has an 86 Ford Thunderbird, and she says after driving for a while, it acts like it is bogging down, or struggling for gas. Fuel pump, or catalytic converter
Ask her if the check engine light is lit up on the dash.
Well she said the check engine does not lit up
Sounds like a vacuum leak, but her best bet is to get it into the garage for diagnosis. No easy fix without looking at the car and hearing it run, especially going through multiple emails, texts, online and a few people to boot.
