car is acting weird... input please

[kriegular]

so here's the deal... i got my car back a couple days ago and it would run great for about 15-20 minutes and then it would start getting shaky at low RPM's and would not build boost or hold an idle. So bad sometimes the car would die, and after restarting it, it would run fine again for another 10 minutes and then the same thing would happen. The check engine light has been on since i got it so i changed the plugs and wires and reset the ecu by taking the battery off the hook. Thinking this would fix my no rev and no idle/boost problem, a friend of mine and I started messing with the S-AFC... now the car will barely even move! It wont hold any sort of idle, has trouble starting. I set the afc so that everything is flat and the car is still acting like crap... Pretty much everyone of the mods on my car was put in at the shop ( except for; exhaust, clutch, t-bo timer, gauges).

another thing, the guy that built the car said that the temp sensor was bad for the gauge on my 3 pod pillar, would that effect the stock gauge in the bezel... cause both were reading off the charts. when this would happen if i wasn't near home i would take it easy on the car and shut it down for awhile before driving again.

Anyone with any suggestions or input please fill me in, I haven't driven the thing in 2 years and this sucks to get it back and run like crap.

Thanks a lot

okay here is some additional info;

i pulled the plugs and they were fouled up so i cleaned them off and started the car again. ran into the same problem... i pulled the plug wires one at a time and it turns out cylinders 1 and 4 are not firering. so i the car is running on 2 and 3 only... what could be causing this... a few people ive talked to say that this could be from the 6 bolt CAS messing with the ecu, but i don't have a C/E light when this is happening. so i searched and found the remedy on here... i will try it and see if it works then get back to you guys...

If anyone has any other suggestions please let me know.
