Question about 1991 Chevrolet S-10 Blazer

1 Answer

Engine missing and bad idle,

I've replaced the distributor cap, rotor, wires, and sparkplugs but still when the engine gets up to temp its starts to miss and idle badly, and upon moderate to hard acceleration is misses bad and runs like crud, ive adjusted the timing once already as it was off by a good amount and that helped for a while. the other thing is right where the plugwires comedown on top of the sparkplug, its arcing out of the boot to the metal hex of the sparkplug where you put the socket to take it off. I have dialectic grease in the boots and the wires are brand newAccel 8.8mm wires

Hey, i may be able to help you,you should just let me know if you have a auto timing or normal manual timing,
in other words,do your ajust the timing on how fast you are driving or not.

About your wires arcing out of the boot,dialetic grease is a real good thing but as soon as it gets wet it tends to get thin and then leads away your spark.
Clean them off and use it with out the grease and see what happens,

you can also try and spray the plug on that metal hex with a clear coat and also around the plug hole...

Hope this help you...

Regards.

Possibly a plug wire or cracked distributor cap. I'd take a spray bottle and while it's running (be careful not to get your body parts in danger of the fan) spray some water on the cap area. If everything seems fine, you could spray down each plug wire at a time. See if you find the culprit that way. For a vehicle so old, if you haven't done a tune up lately. It's probably a good time. Replace the distributor cap and rotor. Plugs and wires.

My car will crank over but will not start.


Try some starting fluid spray,If you get no reaction at all you might have a broken or slipped timming belt.
Look inside the timming belt cover housing if you can.
Look to see if the belt is there or if it moves while someone cranks the engine.
Good luck,pls. vote for this answer

We changed spark plugs, wires, distributor cap, distributor button, etc. We unbolted the entire distributor assembly and pulled it out from the engine. We now can't get the car to start or run. How do I...


Does "entire distributor aseembly" include the metal gear shaft??
If so, you must remove the distributor again and re-insert it in the proper gear groove.
Normally, you "mark" the distributor and the engine with a marker before you remove the shaft so that you can replace it so the gears mesh in the correct position.

You can use "trial and error" to reposition the distributor or you can:

1. Turn the engine to the "Top Dead Center" (TDC) position so that the distributor rotor points to the #1 cylinder sparkplug wire.
2. The rotor on the distributor shafdt should be positioned to "point" to the #1 sparkplug wire.
3. Re-insert the distributor gear shaft.

Please comment if you need better detail...
