help! idle jumping 1800 to 2300rpms

[gotaloveRWD]

So I just put in my engine and megasquirt now when i splice into the fuel pressure regulator vacuum line the car is running too rich and I got fuel coming out of the vacuum line
So I switched to another regulator I had and now it's surging from 1800 to 2300

UPDATE
so now I put on the correct m50 tps and Iat sensor so throttle response is good but idle still isn't fixed
It idled and ran fine on the stock ecu which doesn't make me feel their is a vacuum leak
It seems as though their is too much vacuum going to the map sensor
Any advice is appreciated

And on a side note i got the engine and ecu from myster-e (shant) so I'm trusting everything is correct with the magasquirt
Thanks!

Any ideas would be helpful!

Well since no one had any ideas looks like I'll be spending a butt load of money to have a tuner check it out

What did you find out?

how is your idle organized?

If you have fuel comming out of the vacuum line you need to replace the FPR.

I have a 3000 rpm idle with my ICV installed....adjustments in MS2 do nothing, and there is no change with the ICV plugged in or not (I have 3 x valves, 2 of which are brand new). Could the TPS be causing an issue? Whenever I set the TPS values in MS2, I can see it open fully and closed fully, but I don't know if the ICV takes its inputs from the TPS?

For 3 x months, my car ran fine with the ICV. Went out and started my car one morning and it raced to 3000 rpms....I'm not sure what else it could be beside the M30 auto TPS I'm running
