Alright.

I am getting really sick of this. Whenever I get my car warmed up and safe to start red-lining...it starts to act up.

It will pull really nice all the way up to 7k rpm, but will just drop all the way down to 500 rpm and usually stall if I don't feather the gas a bit. If I keep it running, it usually stays running, but if it stalls, it won't start for like 30 min.

Any ideas?

chech the fuel pump prefilter, could be the problem.

Maybe something with fuel injectors? Does it flood when it stalls out and won't start again? Also maybe TPS (that is really a guess tho)? Good luck man!

The TPS was adjusted using the home made tester and the lights seem to operate fine.

The injectors were justed serviced back in December through Marren Racing in CT. They had over a 10% spread, but are now balanced and blueprinted to within 2%.

The fuel pump pre-filter has not been checked (now on the list) and I have a new in line fuel filter to install. It is due for a new one anyways.

It seems like it is running kinda rich, but not sure why it would start to do that.

Yes, it does have a hard time starting when hot, but not when cold. Early morning, she fires right up without any problem. I am thinking either the ECU needs re-soldering and is giving a false WOT signal to the injectors, causing excessive fuel consumption and to run rich, or a temp sensor telling the ECU it is too cold and thus........WOT and rich, etc.

I just bought a new inductive timing light, going to set that properly, re-adjust the TPS again (after timing) and then clean the BAC really good, just for good measure.

Any other suggestions for maintenance/troubleshooting?
