Hey,
When I drive for 45 min + my service eng. light comes on and the car has no power. The idle is fine (does not miss or anything) but when I take off I have to give it gas slowly(cant go over 1500- 2000 rpms) or it starts to cut out and has no *****, but will get up to speed slowly. When I put the jumper wire in 33 comes up. It has new maf & relay. The fule pump is making a hummmming noise could this have anything to do with this. It's
kinda like it's starving for gas but I don't know???????????????????

Thanks

check your tps voltage.
should be .54 vdc.
if it is high it can give a code 33.
what relay did you change, there are 2 maf relay,, maf power and maf burnoff.

 

Like Ron said , check the TPS.

Have you gutted the MAF? I got a code 33 after gutting my MAF, tried to reset the ECM but it didnt disapear until I put the first screen back in.....
