so i had the check engine light on and i ran the codes and it came back with p1128 and p1130. MAF from what i understand researching. I bought the torx tamper proof bit size 20 and the can off MAF cleaner. I took it out making sure i touched nothing. I sprayed the entire peice very good and let it dry for a few minutes. I put it back in and now the engine is running poorly. when i hit the gas hard it does not move the rpms. It is funning very badly. Anybody have any idea whats wrong. the battery was disconnected before I started and i reconnected it and plugged the OBDII into it and it said no codes. I am not sure what is going on. Thanks John

ok, i think i may have done something i was not supposed to. i sprayed when the connectors are also. what this a bad move?

I started the car without it plugged in and it was back to good. So I will have to order one from the mainland. It will take a week to get it most likely so my question is can i drive it without one until then?

Good and Bad new,

I will start with the good. I remembered a guy that lived here that owns a Boxster that is not running. He has parked it and is going to put an electic motor in it so I bought his MAF sensor which was installed but has no miles on it for 120 bucks.

I went to pick it up, now get this. He lives 40 miles away. I put the old MAF in and just left it unplugged. I got no codes on the way and the car ran perfect. I get there install the new one. Plug it in and the car is back to running perfect only problem now is the check engine light is back on AND i am getting two codes now p0102 and p0112. Seams to have something to do with the MAF again but I am not sure exactly what to do. I drove the car back another 40 miles and the light stayed on but it ran fine.

Anyone have any sugestions.

This is such a PITA!

What year was the car you got the MAF from? There are a couple of different MAF's available depending on what year the car is. I am pretty sure they are not interchangable.
If you haven't joined RennTech yet, there is a good DIY on how to check the MAF for proper operation.

It is from the correct car. The part number is the same. He had a 98 i have a 99.
