1G Car almost turns over

[Malrun]

Back story: Previous owner had a larger turbo but it failed. (Bullseye -unknown spec) He put on a 20g and he said the car started running rough due to more air.

Will this turbo cause the engine not to run at all? When it does idle, hitting the accelerator will bog it down and kill it.

I found one of the injectors to be bad and swapped them out today with a new set that was the same flowrate. Car has spark on all 4 cylinders. I also swapped out the ignition coil assembly for a new one because the tach doesn't work and well, it was there. The car is on DSMLink and the cable will be in tomorrow.

It has fuel pressure.
No boost leak.

I need some help trouble shooting. When I get the link cable tomorrow, what can I look for that will also aid in troubleshooting. I'll be up for a while tonight scouring the forum and testing out potential solutions. Anything is helpful.

Thanks.

Start with a basic boost leak check. No a different turbo will not affect idle. Not even a little bit.

this is one thing I looked at and didn't actually buy. I'll get one now. Thanks

Did a boost leak test and no issues.

What’s it do when you unplug the MAF sensor? I’m also curious if the TPS is reading properly or not.

You might be on to something with the TPS. The harness that attaches to the back side of the Throttle Body was disconnected when we drove the car onto the trailer. I didn't know what I was plugging back in until I looked up the part just now, found the TPS and followed the wire. it goes to where it plugs into the back of the TB. Honestly, I feel it might run slightly better with it unplugged. I have a store close to me I'll pick it up at and try that.

Post a log, running if possible.

I can't get ECMLink to connect. I'll try again tomorrow. Once I get logs, I'll throw them here.
