Idle issue - drops rpm but recovers
So my '87 runs great down the road, no issues, nice and strong. However sitting still, in gear (auto trans) she will idle and suddenly the rpms will drop, but she'll "catch it" and recover. She'll do that once or twice a traffic light, never quite dying each time. If i put her in neutral the drop in rpm isn't as bad.
I have checked vacuum lines, air flow, and the like but found nothing. Thinking it might be the fuel pressure regulator. I have never replaced it or or the fuel filter (but have only had her for 7 months). Thoughts? |
