Tach RPM Issue

[RED TREAD 97]

I've already seached it with no apparent solution. I washed teh motor on my GST on Saturday, it sputtered a couple of times that day and it worked well after that. 2 days later I cant even drive 2 miles with a bad bad sputter and no RPMs on the Tach... Would there be a chance the Crank Position Sensor be gunked up? Or is there something else that would cause both problems?

Probably got water in the cam sensore, or maf.

Have you check your ignition power transistor.

Have you check your ignition power transistor.

where on the car is that??

where on the car is that??

The power transistor is located to the left of the ignition coil pack when looking at the engine from the front of the car. One side of the transistor bracket is bolted to the coil bracket. However, you probably got either the ignition coil or the cam angle sensor a little wet. That could cause the slight missing.

I hosed own the CAS and the plug that goes into the coil pack with WD40. It worked for about an hour and about 15 miles, it started up again. Should i take off the belts, and clean off the Crank Position Sensor? I love my lil DSM so much can't stant to hear her sick.

You most likely got water in the CAS not the CPS. Both CAS and CPS are needed for spark timing. Coil and PT for spark. Tach is from PT. Clean all these and their connectors.

It really looks like I shorted out the PT. I had to order a new one... Not cheap!!! I'learned my lesson though. I did, by the way, check the CAS CPS all respective connections clean them blast'em with electrical parts cleaner but still have the problem.... the PT comes in on monday... I'll post results.

it was the power transistor.... works great now.... thanks much guys

thanks u guys just talk to alex the tuner and got home and maybe found a answer to my problem
