Primary injector fuel cut help!?
 
So my primary injectors have randomly cut fuel on me.. i have my TPS adjusted perfectly on the Ohms level and ive checked the voltage as well everything checks out.. the car will be running great and fine and dandy then randomly it will cut fuel under load, off load, at idle. im kinda stumped on what it might be.. maybe wiring harness somewhere?? let me know what you may think it is:scratch:

S4 or S5 or is the car a hybrid (mixing and matching harnesses etc.)?

injector clip or a failing TPS, just because it reads properly at idle and WOT doesn't mean it may not be dropping out at a particular throttle.

My car is an S4 with an s5 engine swap no ac, everything is deleted off of it even the OMP. Im trying to figure out weather i should get a new engine harness, the car ran amazing a while ago then driving it on the freeway home about 70mph.

I was leaning twords failing TPS and i know my injector clips are the original and definitely need replacing. Is there anywhere online or somewhere in town where i can buy such things as injector clips for an S4? Also i think ive read somewhere where you can swap one of the sensors on the S5 tps since the S4(my chassis) only has the narrow range and not a wide?

if it winds up being the injector clips i have a bunch of the 86-88 low impedence clips, some auto parts stores also carry them. a bosch EV1 connector is equal to these denso injectors.

replaced both clips and saw that my injector wires were also getting pinched between the throttlebody and the iron so i moved wires put everything back together and car runs perfect now! thank you everyone that replied!:nod:
