Hi,
I have 1998 Ford Ranger, 4 cylinder and when istart the engine and run it for a while I have no problem. But after the enginie is warm by excelaration around 30 miles an hour I hear a rattleling noise time to time, and then goes away and the car speeds-up normaly and smooth. Please advise what can be the problem.
Thank you so much for your help.
Donna
