It sounds like the distributor is not clocked in right and it needs to be set properly. There is a mark on the distributor housing that the rotor should be pointing to when the engine is on top dead center. This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.

1. Place the engine at top dead center.

2. Look under the distributor cap and find where the number one terminal runs under the distributor cap, and then match where that position is on the distributor cap with the distributor housing, and it should match up to a mark or a notch on the distributor housing.

3. With the engine on top dead center the ignition rotor should be pointing to the mark or notch that is on the distributor housing, if it is not then loosen up the distributor and turn the distributor until the ignition rotor is pointing to the mark or notch on the distributor housing, the engine should now be static timed.

If you have any high idle problems after the distributor has been properly set then it will be from a vacuum leak.

I hope that this information was helpful to you in any way.

It might be that when you reassembled it that something is wrong with the lifters.. did you label everyone and put it exactly in the original position? very critical that this be done because of the different wear on the camshaft lobes. all components should be put in exactly in there original positions. this is just a thought.. maybe someone else can come up with an easy fix for you.

How do i open the hood on a 1998 chev silverado if release cable is broken


The best way is to reach up from underneath and pull the lever that the cable is connected to while someone pushes down on the hood. This should release it. I've seen some ppl bust a piece of the plastic grill to get to it, but there is no need. Good luck

Most likely the intake gaskets are bad. they will sag in the middle over time and allow a vacuum leak between the head and intake. recommend replacing the gaskets with the steel instead of plastic ones.

Engine runs extremely rough, seems to be fuel related, new fuel pump & filter installed, pressure good, run 2 bottles of injector cleaner through. Can't get to stay running under load. 1998, chev....


Have you changed the plugs, if any are fouled out or if any are worn, it takes more to fire it under load and may be spark knocking because one of the plugs can't fire off all the gas and cause it to skip or idle rough.

I would test for a leaking intake manifold gasket. WITH A WATER SPRAYER , and the engine running at operating temps and at idle, spray some water where the intake meets the cylinder head. If you hear a little SUCKING SOUND, and the engine smooths out temporarily, thats it Hope this helps
