Hey fellas i have a 1jzgte motor with a PLX300 wideband stock twins, injectors and intake, 3 inch down, to 3 out. I have had issues with the car happen over the last 4 weeks.
I have not pulled codes. My buddy and I are going to do that tonight.
i ran out of gas 3 weeks ago. Filled it up with gas and The car started to sputter and loose power a few times the next day then went away .It sputtered a few times but it was typically right at the beginging of driving it and would go away. 2 fridays ago i almost ran out of gas again but found a station next to my office that only had 85 (dang) well it ran fine. then i let it sit over the weekend and didnt drive it. Well Monday morning last week i fill it up with 10 Gallons of 91 and less then a 100 yard driving after that my car begins to sputter and bog down.
well i make it to work with a minimal amount of this sputtering but it was similar to before when it sputered a week earlier. then i worked all day and drove it in the afternoon and it was bogging really bad and loosing power the AFC was reading 15 then 18 then 12 . then i could put it under load and it would leavel out then at about 4300 it would read at around 12 then jump to 15 when it would shutter bog or loose power.
satuday i swaped in a welded diff and tryed to run it in the gerage that night It backfired Sputtered and wouldnt stay on it would actually run at arounds 900 rpm then drop to about 75 prm then bounce back up. i think it would have stalled if i wasnt pushing down the pedal. I could ppush down and it would idle around 1500 then drop about to around 1300 and back fire about every 5 times it would reduce in RPM if i gassed it it wouldback fire.
so sunday morning i get it started and it ideling at 900 so i out some fuel injector cleaner in it and drive it to the Gas Station with minimal sputtering fill it up to the top with 91 so the Fuel injector cleanor has enough fuel to work properly and i dive it back and forth a few times on the road in front of my house it Sputters under load back fires , then hits perfect then i let off and then push back down and i loose power the AFC goes crazy and reads 12 then 15 then 12 then 15 so i nurse it home and in the gerage.
i put it on jack stands with the front lifted only and ran it for about 25 seconds while trying to hold my hand over the top intercooler pipe coming off the turbos to see if i had a boost leak, it didnt sound like i had one and there was plenty of suction but it still didnt stall out.
so i shut it off - hook back up the top pipe.
and try to start it again...................... nothing i tried 12 times and i have nothing it dosnt event read a single rpm on my tach.
Please help if you can. I have a drift event in exactly 13 days and i have ot get it ready. This is also my daily driver
