no need for a new one. just clean it with maf cleaner... or find one used on here. however to test it you can unplug it and if it runs better then you know thats your problem. if it runs worse when its out then thats normal.

also the big flashing SEARCH button will help you. there are many, many topics on idling issues.

Start with the basics.....first off vacuum leaks....even the line going to your brake booster. If no leaks do as mentioned above.

Do you still have the problem once it's warm?
