ok i have a p1133 code that comes up every now and then, also i have throttle issues when i barely give it gas slightly revs up and down this also happens when i hit a slight incline if its a steep incline it downshifts which i know is normal but stops doing it. i removed the MAF sensor when i swaped the engine could this be causing it or maybe a bad pcm tune? please help

 

P1133 is O2 sensor. I'd start with replacing that. And you're not running a MAF?

 

The car is designed to run with a MAF sensor. Disconnecting it is a short-term test (as you will not get proper performance out of the drivetrain).

I think for starters, I'd put the MAF back and drive it a short while (for the PCM to re-adjust).

 

whoops sorry removed MAF screen aka honeycomb screen, nitehawkjcb i remember you telling me to get a new 02 a while back i did and no dice bro issue still exists, new 02 sensor, i seen somewhere if you remove this screen (honeycomb) it meses up your MAF readings could this be causing my **** headache? what does removing your MAF do as far as diagnosing?
MPS 3.2
intense stage 1 tune
1.9 yella terra rockers
SLP headers
3inch DP
Dynomax 2.25 cat back
Walbro 255lph inline
Custom FWI
MSD coils
Autolite 103s

 

so what could be causing this c'mon guys please help me out

 

There are 2 oxygen sensors. You may need to replace the other. And if you remove the MAF and the issues go away, you need a MAF.

 

ok so if i disconect the MAF and the hesitation stops its the MAF, but if it doesnt probably the O2 sensor/s right? ok ima try it out thanks guys wasnt sure about the whole MAF removal deal thanx...

 

Correct.

Maybe. Could be TPS, IAC, or a plugged PCV also...

The MAF screen is another story. I wouldn't do it, I believe it helps with air flow, but check ClubGP I'm sure they've had some in depth conversations about it.

 

P0133 is triggered by slow circuit response of the bank1/sensor1 O2 sensor. The air/fuel ratio is not being adjusted correctly by the signal from the O2 sensor. Even so, it will usually not cause drivability problems. Several things can set this code:
Bad wiring
Exhaust leak
Air intake leak (downstream from MAF)
Defective O2 sensor
Defective MAF sensor

 

Might be a clogged catalytic converter
