What did I do??

[Andrew Tilson]

ok out of Ideas and very out of cash, I took the front of the engine off, and put another timing belt, CPS, and water pump then I took the intake off and the valve covers to fix one of my oil leaks, when I put it all back together it runs very badly worse than before. it idles real low like 500 rpms, if you try to give it gas it pops and misfires in the worst way. what did I manage to screw up this time?????

My guess would be timing belt on wrong, a severe vacuum leak, or the plug wires are on wrong.

sdpatt has posted the spark plug connections and timing belt installation/check before, you can search for those.

checked plug wires and also timing belt is on right left the timing cover off so I could tell for sure

Check that ground strap to the pass. side rear intake bracket and the bolts securing the intake crossover tube. Could be the DIS ground.

ground strap is tight checked ground to DIS module shows .1 ohms so its grounding right, could a vacuum leak caue this by any chance I weas just thinking since I had the intake off maybe?

vacuum leak for sure now, let it run for about 10 minutes today it managed t olower its idle enough to run normally then I noticed that it was leaking massive amounts of oil, my new valve cover gaskets are actually a very expensive oil drain for the motor so I get to tear it down again and see why exactly that is drained two quarts of good oil all over the ground yay!

With the valve cover gaskets, there are some tricky cutouts, especially for the rear bank of cylinders. I would check those out; they are for the camshaft, I believe. Very easy to misplace that part of the gasket.

Make sure your valve cover gaskets didn't get "folded" or "turned under" when you reinstalled them. That could cause a leak point and oil leak to the magnitude you described.
