car won't idle ms4 cam texas speed tune? HELP
Just installed my ms4 cam I had it programmed at texas speed mail order! I have 42lb injectors 255 fuel pump and bolt ons. It will only run if you give it gas. I drilled a 1/4'' hole in the throttle body, I haven't driven the car yet. any ideas? I did put a spacer on the butterfly and it would run then. I haven't adjusted th idle screw yet. Should I drill the hole in the throttle body bigger or what. It also is smoking a little at idle some black and some clear?

I wrote them a note of every single mod I had on my car. I think it would have to be the tune. I got the dots lined up, But once this happens I question my self If i did or not. **** i'm pissed I worked my *** of putting that cam in by my self.

Do a TPS relearn.
1- Ignition off
2- Unhook TPS sensor
3- Open blade via screw (1.5 turn or so)
4- Ignition on (Do not crank)
5- Wait 15>30 sec
6- Ignition off
7- Re-hook TPS
7- Start motor see if it helps.
If not enough, just repeat with small increaments 1/2 tun at a time.
If you open the blade to much you could get a "cruise effect", don't panic just need to take it down.
repeat ALL the steps. This takes a bit of time but will get you by till you go to a tuner that knows his sh*t
