We shall see tonight

 

ya I thought the same thing, visually the belts look fine. I believe the previous owner had them replaced. They do feel a tad bit more loose then they should, I don't think it would be that loose to cause the problems. I could be wrong though.

Thanks a bunch!

 

So the code it came up with is a p0030 02 sensor range and my cruise control light flashes constantly. Thanks again Vladi

Anyone else had this problem??

 

Welcome.
My 1st guess is primary o2 is going bad. Your fuel trims are all over the place. Car is pulling and adding fuel randomly, and knocking as a result.
Next I'd check for boost leaks like we discussed.

*edit: I also thought I saw the wire kinda chewed up near the o2, that's why I kept trying to look down there.

 

Ya if I'm not neck deep in the motor swap on the supra this weekend I'll change my oil and check that sensor out and replace it if necessary. Clean my maf then take it for a boost leak test.

 

looks like it was my bank 1 sensor 1 a/f 02 sensor. That thing was shot, no more check engine light so far and seems to be running fine. Thanks again for the help vladi!

 

Great. You're welcome
