I bought 94 chrysler concorde about 5 months ago..car now has under 80,000 however the car has recently developed some problems as follows: when i turn the car the idle gauge fluates up and down and the car turn off or wants to turn off. Also if driving at low speed at 30 or lower say symtoms may occur...have already changed the spark plugs, spark plug wires, ignition coil, Camshaft Position Sensor...all of these have helped the car run much better but still car stalls or wants to stall since I put a new crank position sensor it doen't stall as often but wants to..What can be wrong with it? Thank you for your help

Your idle surge/stalling condition could be cause by a low idle condition due to a dirty throttle body. You can clean the throttle body using some brake cleaner. After removing the rubber air duct from throttle body, hold the throttle open and spray some cleaner around the throttle blade and housing and wipe with a shop towel. Repeat the procedure until the throttle bore is as clean as you can get it. Once the air duct is back in place you may have a bit of trouble starting the engine but once it is running it should clear up quickly. Good Luck!

If it only starves for fuel, hesitates , surges etc when it's ice cold and you hold gas peddle steady and try to keep running and if it stays running barely then clears up as it heats up- solution--- ...change your - coolant temp sensor- easy fix for for 20 bucks. if it shows symptoms all the time could be map sensor- 25 bucks,..also could be throttle position sensor - $85 bucks--- or idle control sensor- 80 bucks...if that still doesn't work, could even be a bad cat.
