I have had a 13bt s4 rx7 for about a year now, converted it to 5spd manual and done a few other things but I have had a few issues with my idle lately.

I removed my BAC valve a few months ago and just put it back on today to see if it would help... nope, not much difference at all.

All the other emmisions have been romoved from the engine.

I think my TPS may be playing up as it had some strange readings when i hooked up a DMM to it.

I have issues starting the car in the morning after a cold night, it will turn over but wont fire. I have to spray CRC into the UIM to get it started. And from then it wont hold a steady half decent idle until a few minutes later. Im unsure why the AWS is not happening because it looks like the thermowax is still there behind the TB

I have checked for vaccum leaks and cant seem to find any.

When the car is warmed up I'll stop at the lights or something and then my idle will be fairly steady at 1000rpm but then drop to 750rpm which really annoys me because it used to drop to 750rpm perfectly and wouldnt "stick" at a higher rpm for awhile.

I've almost had enough of replacing parts and chaging settings, I just want a steady 750rpm idle

I have searched for idle problems but have not found a thread useful enough yet.
If someone knows of one please let me know or just help me pleeeeease.

If I've missed anything that you need to know just let me know
