HELP! I loose power if pedal pushed down more than 1 cm
ok, me and my friend (Rousuke91t) have both stated having the same problem, I have an 89 TII and he has a 91 TII. my car runs fine idles at 700 nicely but as soon as I get going if I push the pedal any more than like a centimeter the car starts to bog then just cuts out (doesn't do anything) it used to be better (I could push it down like 3 centimeters and get it to boost a little) my tps is only a couple years old, but it might not be configured right, and also my fuel pump has been being really loud, I can hear it loud an clear if I'm stopped and idling. (it's a walbro 255 that I'm not to sure about the installation quality, previous owner installed it, but he said he rewired it) What do you guys think?

"check your TPS voltage at the ECU"
how would I go about doing that?
"make sure the AFM and thermosensor are plugged in properly"
they are
"check your fuel pressure and compression."
compression is 115 on both rotors (5k on new engine)
how would I check my fuel pressure short of buying a gauge?

btw, last time I checked my codes, there was an 01 (trailing coil) but I replaced the coil/wires/and plugs and it kept throwing the code, so I don't know what's going on with that

You ECU might be bad, swap it out a know good TII S5 ECU and check for issues. I know, I know, the S5 ECU is elite, just try it. If the ECU isnt the problem then your wiring harness might have a short somewhere, check all your relays too. Short of that throw in a H22A block, I hear those a trouble free ;-)
