Yesterday I did a boost leak test. I found that my PCV system was blowing air pressure straight out back into the intake hose. It was coming out of the port on the throttle body that goes to the top of the valve covers and then to the intake hose. I was under the impression that the PCV system...

Yes I am aware of the timing issue. I will be getting that adjusted as soon as I have time to do so.

To each their own. This sputtering/breakup problem has been going on for quite a while now, and it was a constant issue. It did not come and go, it was always there. It was there right before I fixed my wiring problems, and then completely gone after I fixed the wiring problems, and still gone...

^Yes the car was harder to start with the loose wires. Also all my lights were pretty dim. After fixing the wiring the car started up much much faster and my lights are much brighter. I ment no attitude, sorry it if came off that way. I just don't see how you can say that its highly unlikely...

Then explain to me why the sputtering problem COMPLETELY went away after all I did was fix some grounds and my battery terminals? That's literally all I fixed and the problem was gone. I would have to disagree. Ground and power wires are pretty darn important. If your grounds are loose you...

what will be back?? The sputtering or the timing? I just tried the process for adjusting the timing about 15 times. Its either at 4 degrees or like 16-18 degrees. I cant seem to get it set at 10* Any Ideas? maybe Im doing something wrong?

Also, found that my timing is only at 4 degrees. So I need to get that bumped back up to 10* seems like my CPS is off by a tooth.

Yes, I was about to go buy brand new plugs again, AFM electronics, possibly new alternator, and who knows what else. Instead, I figured I'd completely check everything over first to see if it still wasn't something simple I was missing. Popped the hood and went through my engine bay for like a...

Well my sputtering problem has been solved!! Turns out my battery ground to the body of the car was extremely loose. Also, the negative and positive terminals were very loose. Tightened everything up, re-did the coil ground while I was at it, and the car runs better than ever! I did read the...

I'll take a look at the back of the can and see. If it ruined my afm electronics then why does the car still run fine aside from the sputtering up top which was already an issue? From my experience bad afm's make the car run like crap over all. Also, is it possible for a alternator thats going...

Ok I got restless and had to go take another look at it. Cant take a picture at night all lost my camera a while back and only have a cheap cell phone. SO anyway, found some weird things on closer inspection. No words or anything on it. It does have the RS-232 DB9 serial port looking thing with...

Yes I'm pretty sure it had a connector on it like that or one very similar. I will take a better look at it tomorrow when I have better lighting and try and snap a picture of it. It was hard to get to and it was velcro'd down under the carpet. Does not look factory to me at all. I've never seen...

The brand is CRC i believe. Designed for afms, mafs, bla bla bla. Anyway, came across something interesting today. I found a weird wire loom behind my CD player. Doesnt look stock at all and it was cut. Looks like the loom from a SAFC or Maft pro set up or something. I followed the wires and...

well I know its not the wires, so I guess i'll look into different plugs. Any suggestion? The car is mostly stock running around 10psi.

I can't remember now if it was sputtering before I changed the plugs or not :S It was a little while ago. I changed the plugs because it had a random misfire at idle and low speeds. Maybe I should use different plugs? I got the NGK BRK6E or 7E which ever is the colder plug is what I got. I just...

I will check codes again when Im off work see if its giving me anything yet. As for borrowing an AFM or TPS no luck there. Not any supra owners around my area.

Well for an update, Just found out its doing it regardless of the ECT button. So not tranny related. I didn't allow the RPM's to go high enough while in normal mode I guess, just noticed it mainly in ECT power because the RPM's jump up alot faster. So its sputtering no matter what mode in high...

Anyone?

Does your coolant level drop any in the radiator? If your losing coolant like you say your car should be over heating. Also if your going off your stock temp gauge it could be incorrect. As for the oil on the spark plugs it could be valve seals leaking down when the car is off causing some oil...

I have a 7mgte with the auto tranny. The motor is mostly stock, has HKS metal head gasket, ARP studs, K&N filter, NGK wires and plugs gapped to .028. Also a 3inch cat back exhaust. The car sputters and has a loss of power at around 4.5-5k RPMs whenever I have the ECT power button pushed on for...
