ok guys so heres whats up! i have done a complete tune up and by tune up i mean spark plugs wires oil and filter fuel filter and run injector cleaner through a full tank of 89 and 93 i have a 1989 GTUs
n/A of course and the problem is when i try to give it full throttle it chokes like horribly bad but if i give it gas through the rpm band like accelrate with it i have no problems but i can only give it about 1/4 to 1/2 throttle what could be the problem im running street port and polish aftermarket downpipe and no cat just test tube with stock mufflers i was starting to think it was a backpressure issue could i be running 0 backpressure and are running into problems? im still learning about rotories so please guys help me out could it be the fuel pump? or something else? like a bad grounding in the engine bay or something?

 

aww come on people lol

 

i dont know **** but here some suggestion.

theres another fuel filter in the tank, that might me dirty.
i think you are suppose to use 87 octane for nas
maybe a bad tsp or bad grounds
maybe the injectors are clogged after cleaning?

like i said just tyrna help.

 

aight cool ill check the one on the fuel pump tomorrow thanks guys and pardon me but what is the TSP yo uare referring to make sureits wat i think it is

 

He meant TPS, which stands for 'throttle positioning sensor'.

 

ooo ok and where exactly is that located on a rotary *like i siad ims till learning about rotary do excuse my noobness*

 

when taking out the fuel pump is there a seal ill HAVE to replace at the top or can i use the same one?
