I've replaced the idle air control valve and thethrottle position sensor and checked for vacuum leaks what else could it be I've checked everything I don't know what else it could be if anyone has any ideas I'm open for anything at this point I'm out of my car because I can't drive it at this point and I'm running out of money xD please someone lol

Purge all air from the cooling system. Set the heat slide to Max Heat and fill the radiator with coolant, until it comes out the air bleeder bolt. If the problem persists, replacing the Ignition Control Module (ICM) should solve the problem. FYI, the BLU wire from the tachometer goes directly to the ICM. Be sure to apply silicone heat transfer compound to the back of the new ICM.

Purged the coolant like you said and id did absolutely nothing still surging in idle to 4500 rpms and the ignition control module is 50$ and it may not be the issue I don't know I've already spent 400$ on the car in 2 days and I isn't got the money to gamble another time I mean is there anything else like anything... head gasket... and no there is not oil in the coolant and no deluted oil just wondering I mean I did get on it really hard before it started happening if that could spark anything I really appreiciate you help man and the ideas please keep them coming

Fluctuating Idle RPM

1. Ensure Check Engine Light is not on. If it is, solve that problem first.

2. Purge air in the cooling system (open bleeder bolt and add coolant or squeeze hoses, depending upon the vehicle). Purging air, or topping off the coolant, solves most fluctuating idle problems.

3. Check for vacuum leaks--examine hoses, Fast Idle Thermo Valve (ensure valve seat is tight), and Idle Air Control Valve (IACV).

4. Check the IACV--If you suspect the IACV is sticking, tap on it with a small mallot and see if the idle speed changes. The "stepper motor," located inside the IACV, regulates air flow during idle. A small pintle fits into a passage, which channels air around the throttle plate. If idle rpm changes, after tapping the IACV, clean or replace it.

Fluctuating idle rpm is usually caused by vacuum leaks (too much air), which the ECM constantly tries to adjust for--hence, the fluctuations as the engine "seeks" a level.

I ended up finding the problem my intake gasket had a 2 inch gap blown out of it and I replaced it myself (: thank you for the help man
