Mass Air Flow Sensor???? HELP PLEASE
Hi all...Yes, I did do a search first for this topic so please don't get angry with me! But I'm really at a loss on tis one and I could use some help, please?!
I've read (on here) that TJ's (I've got a 97 4cyl) do NOT have Mass Air Flow Sensors...HOWEVER, when I called my local dealership's svc. department yesterday a guy in the shop told me they DO have on and transferred me to the Parts Dept. so they could tell me where it was located...I'm told it's next to the manifold. A little vague but now I'm confused.
Do 97 Wranglers have or NOT have Mass Air Flow Sensors?
The reason I'm asking is this:
Engine bogging down, Gas Mileage has dropped from about 18-22mpg to oh um gee...77 miles is now a full tank of gas for me (12 gallon tank) and lest I forget the "GO GO GADGET BLACK SMOKE" that I've got billowing out the back when I'm accelerating. I know it's running rich and I need to fix her! I checked the diagnostic codes and I got P0171 "System Too Lean, Bank 1" and the only error coming up on my odometer is code 12 which tells me the battery has been disconnected within the last 50 starts. SO, tune up was done, fuel injecter cleaner dropped in the tank and now I'm reading that 9 times out of 10 if you just clean the MAF sensor it will solve alot of the problems...of course it could be my 02 Sensor too...
Any direction you guys can point me is sooo appreciated.
