Make sure plug & wire good on # 2 cylinder, something may be misfiring on that one. (that's code 302)
1133 is oxygen sensor, bank 1, sensor 1, should be drivers side, before catalytic converter, but double check at parts store to be sure.

What other codes , need to diagnose those codes before P1133 !
Important: If any DTCs are set (except P1133 or P1134), go to those DTCs before proceeding with this diagnostic table. If the vehicle is misfiring is there a DTC P0300 Engine Misfire Detected code ?

Idles high at start and sometimes durin drvin on 1996 chevy tahoe


P1133 HO2S-11 (Bank 1 Sensor 1) Insufficient Switching

A code like this leaves a 50/50 chance that you either have a bad sensor or a real problem. With a high idle, I would lean towards a real problem. I'm surprised you didn't have another code with this one. It sounds like you are running lean due to a vacuum leak. Check all of the rubber lines that come from the intake. If any of these leak, they can cause the issue you are having.

98 chev 5.7 #3and#6 clys are missing at ilde to about 2500 rpm


I would test for a leaking intake manifold gasket. WITH A WATER SPRAYER , and the engine running at operating temps and at idle, spray some water where the intake meets the cylinder head. If you hear a little SUCKING SOUND, and the engine smooths out temporarily, thats it Hope this helps
