Re: Engine Probs, But Much Rejoicing...

[Ben Patterson <bpatterson@stanford.edu>]

Hey there Ian -

	It's just the tach that seems to flip out, but at the same 
time it's unrelated to the engine issues. About 75% of the time, the 
engine will run like sh*t at start (no power, sounds like it's 
missing like a freak) and the exhaust smells like a motor boat, which 
makes me wonder if it's the knock sensor not engaging. I know the 
grounds are all good, and the wiring/contacts have been hit with carb 
cleaner/dialectic grease a few times. I've got a new fuse box (all 
greased up), a new idle stabilizer, a new distributor/hall sender... 
next up is the knock sensor and O2 sensor. I'm kinda playing the 
expensive guessing game. Nate Pierce says it might be the control 
pressure regulator - any thoughts?
	I'm changing out my downpipe this weekend so I don't pass out 
from the fumes while driving the little beastie, and while I'm there 
I'll drop in the new O2 sensor. Hopefully I'll have time to mess 
behind the dash.

-It sounds like you've got ground troubles.  Is your ground connection at the
-coil clean?  When you say the instruments whack out, is it just the tach?
-If it's just the tach, then your problem is with the coil.  If it's other
-instruments too, then your dashboard ground is having trouble.  As for the
-high idle, grounds could be causing that, but it's also likely the idle
-stabilizer valve.  Take it off and spray it with carb cleaner.

-I doubt the knock sensor has anything to do with your problems.  The knock
-sensor would just retard your timing and you would notice it has a simple
-lack of power.  I think.
