EJ20g Swap problems
Haven't been on here in a while, but if anyone remembers me, my knowledge doesn't go very far at all.
'92 SS. Fozze Ej20g block, WRX ej20g heads, VF39 (bad seals i think), STI yellow injectors, GC8a Apex'i PowerFC with AVC-R, COP conversion, Catless dp.
Sputters and stumbles when given throttle, but drives sorta, only got a minute away from my house this morning before I turned around and took her home.
basically I don't have time or space to try to do anything on it. Curious if anyone knowledgable and reputable would be able to come by and take a look. I'm at the point of frustration between life and this car, I'm contemplating just selling the damn thing and cutting my losses, but I really don't want to do that.
I have beer, and food, and some money. Located 98155.
Mods- not sure if this is in the right category or not? Apologies if it isn't.

Re: EJ20g Swap problems
Do you have FC Datalogit or the Power Commander to tune the PowerFC? Hard to say with an aftermarket ECU if the tune is properly set up or if it is a hardware issue.

Re: EJ20g Swap problems
Have u thought about just getting the 20g Ecu and a robtune? Kinda simplify things a little? I'd help but I just don't know how much help I can give....electronics aren't really my thing

Re: EJ20g Swap problems
If I had a dollar for every time that's been suggested lol. I suppose I'm just stubborn? Granted, the tune isn't perfect and needs some adjustment, but as of this morning the car barely idles and barely moves down the road, so it seems like it's something bigger.

Re: EJ20g Swap problems
Maybe a bad injector or coil. Listen to see if all the injectors are firing. Also check to see if the coils are firing. You can also just unplug the injectors one at a tie and see if the car remains running or gets worse.

Re: EJ20g Swap problems
Use the diagnostic screen on the commander to make sure all your ECU inputs are working and withing range.
Sounds to me it could be the temp sensor or TPS not reading properly. Especially if it happened "overnight".
