Question about 2001 Chrysler Town & Country
Runs rough, poor gas milage. Problem code indecates random missfiring. Have been to two dealships, Pepboys and three independent mechanics. One dealer said it was a burnt valuvebut compression is good on all cyl.(170). They replaced plugs,plug wires,coil then said they wanted $280 for more diagnodtic work. Another said computer needed to be flashed,an hour later said it could not be flashed,however the computer was ok. Pepboys said the checked egr valuve,oxygen sensor and cam shaft sensor all were ok, no futher recomendations. One mechanic said injector on 5&6 were bad and replaced them,no change,he also changed fuel filter and air filter agian no change and he gave up. Other mechanic checked the computer and said it was ok as well as crankshaft sensor,and he gave up. the engine has 110 thousand, the problem started all at once but somr times it will run just fine for about 10 minutes and then back to the same stuff. I don't know where else to turn,please help. I have cleared the code several but the same code always returns and check engine light comes and goes

it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.

SOURCE: MISFIRE ON CYLINDER 5.
Same problem. 94 LHS 3.5L engine. Noticeable rythmic misfire at idle. Looks like cyl 5. When I pull the injector connector off of cyl 5 the idle rythm does not change. It does if i pull the inj connector off of any other cylinder. Spark OK. Injector ok using seperate 12vdc supply (clicks). Connector to injector has pulses on it verified with a test light. Inj coil resistanceis 12 ohms, exactly what it should be.
Still need to check compression and intake manifold gasket

This happened to me. The valve that controls the air intake gets stuck which stalls the motor. I removed the air intake hose and wiped it clean using Acetone (nail polish remover). Its been running perfectly ever since....
