I have a 1997 Lumina 3.1 with 100,000 miles on it. When I get going around 50MPH the rpm's drop and the car surges and acts like it about to die. As soon as I give it gas it clears up and drives fine. This has happened about 3-4 times in the last two months.
No SES light, or codes,
Tried replacing Fuel Filter, Plugs and plug wires.
Any other suggestions?
Sorry if this is a repost, I thought I saw something about a month ago, but can't find it now. Maybe it was on a different sight.
thanks
