Satan's Angel

Alright...I gutted my cats and installed rear 02 sims. then the car ran SUPER RICH and had a low rpm misfire. So then I ported the MAF to try to lien it out...now the car runs fine at low rpm but misfires BAD at WOT. I had friend at a GM store hook it to the tech II and these are the codes i am getting0300,P140,P0151,P160,P1153. Thanks much in advance to anyone who can help...THIS IS DRIVING ME CRAZY!!!!!! <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

If you go into the Computer and Diagnostic section, there is a big red button at the top labled, "SES Code Translator". You can click it and enter your codes.

Basically:

P0300 Engine misfire detected

P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2
P0151 HO2S Circuit Low Voltage Bank 2 Sensor 1
P1153 HO2S Circuit Insufficient Activity Bank 2 Sensor 2
P0160 HO2S Circuit Low Voltage Bank 2 Sensor 1

Are you sure you plugged the O2 simms in to the rear O2 simms? Do not plug it in the front ones. I know that sounds stupid, but this is a start.

Sounds like what Eric said, or the Sims aren't working right as O2 sensor 2s are the after-cat sensors...???

Icut the black center piece out the MAF...it that maybe the problem???The 02's are plugged in correctly.

Another possibility...

your O2 simms are no good.

I bought some a couple years ago...installed them, car ran like total ****...very much like what you are describing. The simms were no good brand new right out of the box.

You cut the black center piece out,the one with the sensor wires? I hope not. If you did,then buy another MAF.That your problem. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

Have you checked the codes since you ported the MAF?
