my car has a rough idle... like it will idle smooth and then the rpms will drop when ever its in gear and im stopped... any ideas.?? i already changed the plugs wires

The RPM'* are supposed to drop when you're in gear and stopped


As for the smoothness.......Check your vaccum lines for leaks.

After checking for vacuum leaks, I would say the next step is to clean your throttle body. Does the engine stumble an excessive amount when the AC compressor kicks in?

Good call JDB

If those 2 ideas fail...check your intake bolts and make sure they are tight.

i dont run my ac cause im too lazy to get it recharged but like when its in park idleing it will be idling righ bout 800 rpms and then all of a sudden it will like drop to like 300 400 rpms its like idle surges

u check ur MAF???

Kennginn, maybe you should tell him HOW and WHAT to check on the MAF, with all the proper procedures and warnings?

U can use this link to a thread to clean out you TB as JDB had mentioned, and also for cleaning the small filaments on the MAF sensor to clean them.
BE CAREFULL WHILE CLEANING THE FILAMENTS!!! THEY ARE EXTREMELY FRAGILE.

im not retarded maf mass air flow sensor....and its not that

Well now that we got that out of the way.....Jeees.....

Anyways, clean your TB yet?
