Drastic drop in MPG
ok this started occuring around the time i cleaned my MAF sensor. I used to get around 140 miles in the first set of bars on the meter. but now im getting that around half full. That is an extreme difference. I cleaned my throttle body and put in some fuel injector cleaner but thats it. I always use premium gas(93)which is 2.38 a gallon so its definetely hurting my budget. Could i somehow messed up my MAF i guess ill go check that but any other suggestions???
thanks-kyle

When was the last time you changed your spark plugs?


Change them every two years or 30k miles. I know toyota says 90k, hog wash, if you want to stay at peek its 30k.

go with the ngk's! are you driving any differently? Have you been traffic driving a lot more? Hows the weather? Many factors that could be considered

Tire pressure? Did you rest the ECU when you cleand the MAF? Did you clean your IACV? Need a new Air Filter, or clean your Air Filter?

Air Filter looks clean, havent changed driving styles-shifting around 3k, i did not reset my ECU after i cleaned my MAF. i guess i should do that. Would that make that much of a difference?

It could. What about your IACV.

After I cleaned mine I noticed a big gain in gas mileage.

I htink it's an Idel Air Control Valve, but I think all we have is MAF for that. The last IACV I saw was on a Probe/Mitsubishi. Never wanna see that again! thumbsdown
