Question about 1994 Chevrolet Astro
Today while stopped at a stop light, the idle became very rough. After picking my child up from school the van began to surge while driving down the road. Complete tune up a month ago including coil, wires, plugs D-cap, Rotor. and module. This thing feels like its going to die. Once i got home it stated right up but still had a rough idle. waited for an hour and it really didn't want to start at all. the surging idle and surging driving still continious.

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure

I had the same issue with my venture. It turned out to be the number 5 plug wire, backside of engine ended up breaking out of the plug carrier and burning in half on the manifold. Your best bet is to trace all the wires to start off with and change the plugs. If that doesn't help, it may be internal. Good luck

I have experienced this problem on similar vehicles. You should try and replace the coolant temp sensor. If it is not reading the correct temp to the ecm, it will not get the right fuel map. Also, the cts will not always throw a code.

Hey I had my rotor and all that stuff replaced on my 2000 astro van, Intermittently it would not run, The problem was I hit a puddle one day and water flew up on top of the roter like 3 drops, it created a trace( it was arching) Thats why it was intermittent.Take a look at the cap look for like a discoloration on it clean it and put it back on.Sounds too easy but remember I had all new parts too.
