Having some partial throttle missfires and my autometer gauge needles fluctuate (electrical water and oil) durring the missfire. Sound like a ground problem?

 

A couple of guesses:

1. May be old (fouled?) plugs or other ign problems such as bad coils or wires - do you have any high-rpm missing? Any power loss at high rpms and loads? These are other indicators of the same things.
2. Possibly bad ground and/or electrical noise from sparks jumping where they shouldn't from bad HT wires.
3. Maybe, but see 1 & 2.

 

well i am missing a bit a high rpm, but I chaulked that one up to the fact that im still tuning her, but I suppose I should try swappin out the plugs and wires. The plugs are fairly new, but they have been flooded once or twice, I have no clue how old the wires are since I'm the 4th owner. Would a 10:1 AFR at 8psi 6k+ rpms cause a miss? Either way, i think I answered my own question with these plugs.

 

You'd be surprised the many problems that occur because of bad plugs. Most people neglect that as it being the problem and jump to conclusions about other major things.

I had about the same problem with you about missing and poor idle at times. I found out the trailing wire from the rear rotor was barely on the plug and the plugs themselves were old and beat. So i changed them out and put the wires on tight and car ran like new again.

 

sounds more like a short-to-ground than anything else.

most common thing i've seen that does that is an arching spark plug wire.
run the car at night and strap a wire onto a screwdriver (a well insulated screwdriver). run that up and down your plug wires, and over the coils and look for a light show.

if that's not it, a lengthy way to check that out is remove fuses one at a time and try to duplicate the conditions in which the problem occurs.

 

well id have to say it is the plug wires since everything stopped having problems when things dried up. The roads were a bit wet last time i was out. It didnt really come to mind when i originally posted. I'm aware of the screwdriver trick, i never really felt comfortable doing it, lol. Who carries a decent set without breaking the bank. I'm running stock turbos, stock ign. Money has been tight since christmas.
