hi im trying to get help on my swap... I have a 92 hatchback with ls motor that im having problems it runs fine until 4500rpm and if I hit the throttle all the way ill bogg like it doesn't have gas .. I cleaned the injectors change tps have installed 3 different throttle bodies change full pump filter timing I have done so many thing I dnt know whats the problem I hit the throttle all way and spry carb cleaner and revs fine I think its short on gas but why?

help pls thanks

 

A few questions:

Is the check engine light on?
When you replaced the TPS did you calibrate the voltage?
What ECU are you using?
You checked ignition and cam timing?

 

No check engine.. dint replace tps just hole throttle body .. I have tried pr3 p06 p05 and the stock p75... timings its good replaced spark plug cables and cap..

 

If I put my hand half way throttle it revs fine so that why I say it short on gas or 2much air

 

Check your TPS voltage and check fuel pressure

 

What voltage its supposed to have and preasure

 

And I've change fuel pump already.. ?

 

crank sensor?

 

thanks I found out looking at the fuel rail I put 2 washers at the end on one side and the line wasent on the correct spot that's why it wasent getting gas..
thaks 4 the help
