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?

If the timing was off it would it be running I'm wondering if thats what it is now?

If you think it's a tunning issue there is a guy down here in Charleston that can get that thing to idle and have great drivability. He tunned my 231/237 cam and I idle @ 850 with no problems.


Could be off a tooth too?

i thought you had some sort of tune on your car before we put that cam in. still it did start right up and drive good. sounds like TSP did something wrongin the tune.

Are you sure the cam and crank gear were dot to dot? Don't drill the hole much or you're asking for it. I'd call TSP monday and see if they can help.

Did you inform them of the 42lb injectors when they tuned it?

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

Thanks guys I drove it some and adjusted the idle some , and drilled a hole in the blade its running better and better. That sob pulls like hell!!!!1

It will be better if you do a TPS relearn. That is Throttle Positioning Sensor relearn.

Just go through the steps I mentionned.
