So I decided to put some dielectric grease on my ignition components , after doing so my rpm gauge and speedo were not working , So I took loose my coil connections and wiped the excess grease off that was on the face of the plug from apparently putting too much on the tiny connections.

RPM's came back , speedo still pegged at 120 , so I did some more cleaning with a qtip of the male and female plugs I used the dielectric grease on , my speedo is still pegged and I was just out messing with my car yesterday and my speedo was working normal , I am sure I would have noticed if it wasn't.

Which of the connections do I need to focus on cleaning better? The needle jumps when first started but stays pegged.

I put some of the dielectric grease on the AIC valve , each of the 2 connections coming off of the icm , and the 2 connections plugs going to the coil.

ignition coil , i think involves speedo signal correct? for all I know sitting for 1-2 day might get it back working but I think I need to do a thorough cleaning probably.

They sell a spray can of electrical connection cleaner, I bought some for our home stereo, probably older than most of the members here on the forum, the stereo not the spray can. you could try than and wait for the excess to dissipate then plug it back in and see what happens. I hate electrical problems, I would rather pound my balls flat with a sledge hammer than hunt down an electrical problem.

good luck.

The ignition has nothing to do with the speedometer.

A voltage spike on the speedometer can peg it. Due to the nature of the mechanism it will NOT come back around to zero (well... it's trying to come back around the bottom, so all it does is push on the peg).

Get the car up to about 60 and the speedo *should* fix itself.

Alright I'll that and see hopefully it works.

I was just going through the diagrams when I posted that and thought I saw something that could indicate it so figured I'd ask , some of these diagrams confuse me.

I've had the same problem with the speedo once stuck at 120. I figured i could judge speed on the highway by tach.
But once i got up to around 50 the needle popped up and it started working again.
