Question for Pople w\ the supra Injectors

[EricSol]

Jim does have a o2 simulator, but are you sure the o2 sensor is ok? The 3" shouldn't have any effect on the o2 sensor. The only other CEL I have seen from our exhaust was caused by a bad sensor, not the exhaust. I think the simulator is about the same cost as the sensor so I would go that route. I have even heard of some guys running without a cat and not having a CEL, logically you would think that without the cat you would have to use a simulator for sure.

Here are some 1MZ cdes for reference;

I found that my Exhaust gas thing is going crazy too.. that 3in exhaust is making it hard for the sensor to smell the gas or w\e.. so it is setting my check engine light on... anyway around this??
thanks
Scott...
I heard that Jim@foreign was selling a "fake" one or w\e that made it tell the ecu everything's alright all the time.. but I dunno

I think i found the problem.. i was looking at the pulleys that u put in secondly... they had the spacer on the side of the engine... and the belt went all cock-eyed.... I switched the pulleys around, so the spacer is toward the passanger wheel... and it runs perfect.. the low battery light turned off.. and it was weird.. I started it after I put them on the right way.. and like.. S@It load of white smoke rolled out.. and then it stopped after I drove for a while.. I drove around for like 15 min and the cel never came on.. .I think the white smoke was the burning of the coating.. I dunno... I don't think it does it anymore.. btu I thinkt aht solved it... I think its becasue the belt was "lagging" (so to say) and it wasn't moving freely... So I think that solved it.. U think? Ill keep posting whats goin on.. thanks for all the help
thanks

so I figured it out.. when I ahve my AC on and my rpm's are above 1000, the battery light comes on... unless I go above 3500 or 4000... Its the belt doing soemthing.. is there something on the Pulley setup that I can adjust and make it not happen? it would probably be the alternator... but I don't know how to adjust it... help? thanks

IF you have the dynamic tensioner Jim@FA says the belt length is critical so it wont slip. If your having problems he is the one to speak to.

I have that auto teninsor.. or w\e.. but I did have that check engine light come back on.... the code is P0401 it says like.. Exhaust gas recirculation insufficient or soemthing... eI dunno.. what shoudl ID o?

[EricSol]

Its not a o2, its your egr. Its like the tube got kinked or blocked somehow. Double check the egr tube.

which one.. the one on the back header? also.. Jim said that this exhaust is a little quiter.. but it seems to be louder.. it has a mean groul to it at low rpms, but at higher, it gets real loud... regular? just asking, because no one around here has a JP exhaust, or anything to their solara period

[EricSol]

I would check the back one first. Its a 3" stright thru exhaust, it will get loud when your on it. I was more concerned with it being quiet under normal driving and still be able to produce big hp when you are on the gas....so yeah, its normal.

k, sounds good.... is it the EGR tube connected to the back header??? I dunno... I want to get it solved tho.. the light comes on after about 2- miles of driving... so... I want to solve it... thanks for the help

so I thought about what u said about the tube being pinched.. and I thought.. how would the metal EGR tube on the back header get pinched.. then it hit me that the EGR is next to the intake manifold.. and I found a hose that was being pinched.. and I fixed it... to get that CEL to go off.. I have to turn it off again probably right? at least I found the problem and pretty much fixed it.. thanks again
