Two weeks after my car repair(new idle control valve,tune-up, gas/oil filters)I noticed an unusual RPM like my car is going to stall. Luckily my car kept running smoothly. Any ideas as to what might cause this?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Ben If this only happened once then you may have had a piece of trash like a small carbon deposit that fouls have caused clogged fuel flow momentarily. If this is an on going issue contact the repair facility that performed these repairs in further diagnosis.

Audra Fordin, Owner at Great Bear Auto Shop Hello Benjamin, If you were not experiencing trouble before the maintenance was done, go back to the shop where the repairs were done. Perhaps the valve or wires came loose causing your car to stall and not run smoothly. Mechanically yours, Audra

Diane Larson, Owner/Manager at Larson's Service Hi Benjamin, There are many things that may have caused you Toyota 4Runner to feel stally. It may or may not have to do with what you had done 2 weeks ago....:) If the problem only happened that once, don't worry about it. If it is still happening, go back to the shop that did the repairs, it may be something simple: possibly some dirt or carbon is causing a problem, we see a lot of dirty Throttle Plates. oh,oh, make sure you always use good gas! It is so important to keep today's engines clean, using good gas and adding Techron every maintenance check-over, is one of the ways we keep our clients vehicles in great running condition. Cuts down on repair bills and the inconvenience of a poor running engine :) Have a Fun Day!

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Benjamin, Hard to tell. If it keeps doing it I would take it back to the shop that did the work. It's also possible that you just had some bad gas. Sometimes things happen that have no bearing on the last repair you just did. Keep an eye on it and get it back to the shop if it happens again. Lori Johnson
