I have a 89 t2 last summer swapped the engine with the thanks of the banned member japan2la..everything is fine but when i give it a little gas it sounds like its doing this ururururururururur... rather then uurrrrrrrrrrrrrrr....lol sounds stupid but thats the simplest way. I tried spark plugs/wires/fuel filter to no avail. Only thing i havent tried was tps and injectors. Now i read that if you swap the primary injectors they do the exact same thing..so my friend could have done that. But i think its tps or injectors..and no codes btw

 

Limp mode probably. Omp.

 

TPS is out of calibration, the ECU will forcibly try to idle the engine down if it is between 1500 and 2000 RPMs if it does not know the throttle is being applied.

 

As I thought I'll try a different one if the problem still persists. Shes sitting right now until I get a new starter. Also I ment the injector clips if they are swapped could it do anything different?

 

Tps is good and is spot on problem is still there?? Clogged injectors???

 

What you running for and ECU?? Bad OMP?

 

Stock ecu..everything is stock besides full exhaust and intake cone..

 

I believe I know the sound its making.. only because mine does the same thing.
It went away when I adjusted TPS but it came back within a few drives..

 

Hmm well i looked at my injectors and grommets and grommets were hard on the primaries and on the secondaries they were cracked..could that be the issue besides tps?

 

under a load does it still chug or does it pull good

 

Sounds like maybe the turbo inlet pipe came off or is cracked? Causing the airflow sensor flapper to not open all the way and leaning the car when you give it throttle? Possibly charged pipe popped off. Is the are making any boost?

 

Lets say going up a hill it doesnt do it if thats what you ment by load..and the inlet pipe has little cracks but i wrapped it up could it be the o2 sensor? Cause this harness that I got is messed..and also its only really noticeable when the engine isnt fully warm
