Hi im looking for some help or any tips that you guys might have ... I have a 87 pickup thats efi the problem im having is itwill rev to about 1500rpms then shut down but when tps is unplugged it runs fine but no top end .. So on that note heres what i have checked ... The tps has been checked an set to how pirate 4x4 write up said to an pass .. Iv checked all my wires an wiring tried a different maf an no change ... Swapped ecus an no change no vac leaks ... Thanks

 

22re assuming?

Shut down how? Engine off, rev limit, bogs, idles

 

Its a 22re ... It will rev to about 1500 rpms an shuts down like a hard cut when the rpms drop it will kick back up but only has quarter throttle when tps is plugged in .....if i unplug the tps it will rev like it should but is really sluggish at the top end ...

 

Is it throwing any codes? My 22re seemed to do that and it was the air flow meter. Can you set base timing at all? Does it seem to backfire when you rev it up?
