Hello my name is Ryan, I have a 1984 sigma with tr efi in it, and it is not running 100%.this is what I've worked out so far...also if someone knows what error code 4 long 2 short is let me know, 4 long 1 short os injector coil resistance..
So I've searched on the internet for ages...ive spoken to some EFI shops around where I live (I don't think they know what theyre talking about, they want me to spend $200 to plug my ecu in just to check whats wrong with it), ive checked as much as I can..but I hope someone here can try to put something together, this is what I have so far..
Car idles at 1600 on startup, idles down to 1000-1200.
WITH the Throttle position sensor (tps) CONNECTED, at about 1500 rpm, it starts breaking down, or breaking up? RPM goes from 1500-1300 constantly, when I floor the accelartor, it revs up fine.
Tried 3 TPS'S, It got an auto ecu in it, but its a manual sigma, I tried another auto ecu and another manual ecu didn't fix it
Without the TPS the car runs and revs up fine. im at a stand still have no idea what to do or try, please help
Also
. I'm getting 3 codes, knock sensor tps and another.. its 4 long beeps 2 short.. I had a look on the chart and the injector fault is 4 long 1 short.... So if someone knows what 4.long 2 short is, of that means injector 2? Or w.e... But when I turn my car off and back on its like it automatically resets the ecu? I have to start the car for 5 mins then check the codes again? Or maybe its something else cuz I drove it 2 hours ago ignition on then the ccodes were there but I started it turned it off and back on and the codes were gone ? But yea help plox
