94 Camry 2.2L idling very rough and stumbling while driving

[Kentucky_Camry94]

I recently bought a 94 Camry 2.2L LE that had an occasional stumble when at normal operating temperature. The more I drive it, (been 300 miles) the worse it has gotten. The entire car vibrates and the idle will rarely stablize. When at higher speeds, it will sputter but if you press the gas, the sputter improves.(does not disappear) Note: We found out that it sat for 6-9 months prior. NO CHECK ENGINE LIGHT!

Below are a list of things that I have done
Checked for computer codes - NONE
Sprayed carb cleaner (02 safe) to clean IAC valve.
Sucked cleaner through TB
Pulled Fuel pump and cleaned
Sprayed around TB to check for Vacuum leaks - none
Replaced the fuel filter
Has new plugs, wires, distributor cap, and rotor

I have disconnected the plug that appears to go to the IAC valve as well as the one that appears to go to the TPS. This does not change the engine idle...for better or worse.

I am going to clean the EGR valve today. Needless to say, I am very frustrated. PLEASE HELP! Any other Suggestions?!?!? TIA!

Check the coil inside the distributor. They are a known trouble area when they get a lot of miles on them. (You don't say how many miles are on this car.) You will need a digital volt/ohmeter and the specs fropm any manual to do this simple check. Also inspect the coil for hairline cracks. That too is common as they age. If you don't have a manual you can download a Toyota factory manual for free at the top of the Camry forum over at AutomotiveForums.com. Download the generation 3 manual.

Just an FYI. Some vibration at idle is normal for this generation 2.2 5SFE engine. The stutter at speed is not normal.
