more than a yr ago I installed my piggyback pullies. At first I had troubled busting loose the main pulley. I forgot to stick the wrench in the tranny to stop the crank from moving.

so it moved a little, cant say how much but it did.

I ended buying a air wrench and got it all off and re-installed.


Since then I have had a slightly off idle that is really getting on my nerves. It runs fine just not idling smooth as it is suppossed to.

I know it is not the plugs. they are week old. I havent checked the wires yet.

I need to figure it out cause when it is night time and the headlights are on and the A/C etc etc.... It almost feels like it might die due to the low voltage at redlights.

MAF looked fine, cleaned it week ago too.

Is it possible I threw off the timing?

No there is a crank trigger wheel inside the timing cover that handles timing. Not to mention the crank pulley is keyed

You may be having a bit of problems with the battery, exacerbated by the U/D Pullys causeing a low voltage idle/ stumble.... might be a good idea to check the battery for a bad /weak cell, also connections , and the connections to the alternator.... also try the orig. stock alternator pulley if you replaced that too.... good luck

the part about the car idling low was a sidenote that makes the bad idle more noticeable. I am not worried about the battery or electrical on the voltage end. It just is more prevelant when volts are low.

when volts are normal then I still feel the miss. the two are not related I do not think.

I just need to figure out why I havea a miss now. it is not constant and doesnt affect the way it runs but it was never there before. I hope it is just a bad wire.

One last thing. the plug that is on the passenger side closest to the firewall seems to have oil on it when I change them out. maybe that is the cause of the miss. when accelerating the car is fine and the oil doesnt foul the plug. does this sound like the cause? probably so but I dont know that much about the technical side of it.

I would try unplugging the MAF and check idle, just kuz it looks good, dont mean crap. verification of working wires is a must. Make sure there is not excessive antisieze on a plug. Tell us more about the oil you found.

about the oil....dont know what I can tell you. I didnt look at it very closely last time. I had noticed it about a yr or so ago. I change my plugs way too much so I know it was something that wasnt there before. I dont know which came first, the miss or the oil on the plug...

I will unhook the MAF and see and also check these wires soon.
