I have a 2000 Astro had the same troubles.I saw that the sides of the coil were burned looking.In between the bar that goes around it. This started around 110K It would run badly when wet or high humidity.Then throw up the check engine lite.Put on a new coil so far the problem has no reocured.

I'd check for vacuum leaks next. use a spray can of intake or brake cleaner. spray around vacuum lines, manifold gaskets etc. if the rpm increases you found a leak.

SOURCE: where is the coil located on a 99 chevy astro van?

You have to remove the interior dog box and the distributor and coil assemblies are in the back of the engine behind the upper plenum.

Ok I will be a little more specific,1998 Chevy astro van runs rough. Was diagnosed as a tune up so now has all new ignition parts (cap,rotor,distributor,ignition coil,spark plugs) fuel system completely...


I don't know how you determined that you aren't getting fuel to those cylinders but if that is true, you now need to determine why. You have to determine if those injectors are receiving power supply and pulse. You also need to first verify fuel pressure. This engine will give you a world of problems if the fuel pressure drops below 55PSI.

Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.


I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

You've already eliminated the spark plug & wireset, distributor cap & rotor.
Sounds like your car needs a tune-up, specifically, the PCV (positive crankcase ventilation) valve, and/of the EGR (Exhaust Gas Recirculation) valve.

Components checked/replaced during a tune-up are:
air filter
motor oil
motor oil filter
breather filter
fuel filter(s)
fuel strainer
PCV valve
EGR valve
spark plugs
spark plug wires
ECM or distributor cap & rotor
cabin air filter
transmission oil filter
transmission oil
engine coolant
check all vacuum hoses and lines

Dodge stratus misfire, runs rough has random misfires in cylinder 1,3,and 5 and a vacuum leak, I,m not too worried about the leak unless it is related to the misfire


I WOULD REPLACE DISTRIBUTOR CAP AND ROTOR.MARK LOCATION OF ROTOR OR MAKE NOTE SO YOU CAN INSTALL NEW ROTOR IN CORRECT FIRING POSITION. IF THIS CAR HAS A LOT OF MILES I WOULD REPLACE DISTRIBUTOR CAP, ROTOR.SPARK PLUGS AND WIRES.REPLACE IGNITION COIL.CLEAN FUEL INJECTORS, FILL GAS TANK UP TO 3/4 TO FULL TANK OF GAS POUR CAN SEAFOAM IN FUEL TANK IT WILL FLUSH OUT THE FUEL INJECTORS WHILE ENGINE RUNNING OR DRIVING CAR. REPLACE FUEL FILTER. REASON I SAY DO A TUNE UP PROBLEM COULD BE MINOR FIX.COULD NEED TUNE UP.IF TUNE UP DONT HELP THEN YOUR PROBLEM IS DISTRIBUTOR OR THE CAMSHAFT SENSOR INSIDE OF DISTRIBUTOR.THAT WOULD SET OFF CHECK ENGINE LIGHT.BUT I WOULD SAY TUNE UP COULD FIX PROBLEM.

1993 Plymouth Voyager will not crank


Remove the Distributor cap and watch the rotor as you crank the engine. If the motor is turning over and the rotor is not moving then you have a broken Timing belt. If this is the case the Belt broken while the engine was running. I can tell you from experience, I owned one of these and mine did the same thing, Every valve in the head is bent. The good news it is not hard to replace on your own and it can be done without removing the engine. The bad news you have to remove your head and have it serviced by a shop.

Dont know what the problem is


Check fuel pressure and check for spark and check that the airflow meter is operating, check for timing as well. Check for any wiring problems(loose connections, corrosion, condensation in distributor cap. Check distributor cap+rotor plug wire from coil to distributor. Check for any worn or damaged wiring or bad ground wire contacts. Air, Fuel, Spark and Timing are the key elements for an engine to run.
