Ok as some may know I have been having issues with my TII since I bought it a little over a month ago, I have deleted all emissions, and the thermowax and a full exhaust and has a pre-tuned ECU in it and was running into every now an then the car not revving over 2k rpm.

So I have changed the thermostat, coolant temp sensor, and the AFM and re did all the ground wires in attempt to get somewhere with this car and I have also re stabbed the CAS to re do the timing and every time I touch this car it gets better then gets worse.

So now my issue is it starts and I have to keep my foot on the throttle to keep it running or it dies out, and at the same time if I give it to much throttle the car shuts off, but if I ease into it, it will rev all the way up, if I could get a leadway on what to check out next before I loose my mind would help, Thanks.

Is the car a s4 or s5?

Oh, sorry its a s4, its a 87 tII but has had a jspec engine swapped into it

Check for vacuum leaks.
Never fails, after "I did an emissions delete"..that is followed by "why is my car doin this?".
cute couple.

I personally really like having a working thermowax and BAC
Its nice not having to step on the gas to keep it running, or just to start it even.
The stock cold start works just fine on my half bridge. Like a bawwss

Well I would think a vacuum leak because my emission delete but the car has been not running right the whole time I have owned it for almost 2 months now, I replaced all the vacuum lines when I did the emission delete and re made new fuel lines as well and being a jspec i know the fuel lines are backwards because the FPR is on the bottom, and I even got rid of the pulse dampener on the top rail. But it got worse after I did a thermostat and coolant temp sensor.

check the voltage at the fuel pump and as well the line pressure off the fuel filter.

the jspecs orient the PD and FPR in the same order... so i'm not sure what you deleted. the rat's nest fuel lines however are routed backwards to the inlet/outlet(which you deleted?).

santorkyle

Yes I deleted the rats nest and ran new 3/8 fuel injection hose to the return on the firewall, and to the fuel pump, so the line from my fuel pump runs to the top rail and the return is from my bottom rail since on jspec the FPR is on the lower fuel rail. But I am glad once again for your advice rotary evolution because I took my fuel pump out a few days ago just to look at it, and the power wire was messed up so I fixed that and cleaned out the fuel tank and put some 93 in it with some 2 cycle oil since my OMP is locked up and just got the rebuild kit to it the other day. I maybe wonder if the 2 cycle oil in the fuel (pre mix) might be giving me issues?

Ok so I put my stock AFM back on the car and it started running normal again, adjusted my idle to run but did not re adjust my TPS back in range yet but it idles fine, now the issue I am having is that if I drive and get into it and hit boost the car will go into limp mode until I turn the key off and then back on, then I can drive it again normally, so I don't know if it because I have the boost sensor plumed into the blow off valve and then into the intake manifold, or if it is because I don't have a restrictor pill in line with the boost sensor. Any more help from anyone would be appreciated.
