Hello just wanted to throw a quick question out there. I have a 93 talon fwd non turbo, last week the check engine light came on a couple times with a small hesitation but seem to be driving normaly. I went out one morning and go to start it, it fired but ran very ruff the light came on then it shut off tryed it again and the same thing happened. I pulled the plugs, number 1 and 4 plugs were black soot covered number 2 and 3 plugs were clean. After trying to start the car a couple more times all 4 plugs became wet. So I decided to change the plugs and wires I had no luck the new plugs became the same way.I checked all fuses and timing and seem to be good. I just thought it was weird that one day it was working fine and a no go the next day. I was told it sounded like a o2 sensor. Any thought? Thanks

with your check engine light on, get an obd2 scanner and find out what DTC's it's showing. Then google the code or post it here. Most guys here run Link and they'll fire off a nasty reply like "you have a dsm, and no link?"....just saying lol

I Highly doubt that. No one will give a "nasty reply" besides its a NT, why the hell would he need link.

But like Mike stated I would start of by scanning the car and finding out whats causing the CEL to come on. Around 30-80 bucks (depends were you go).

No obd2 are 2gs. 1gs are old school I use a old school laptop with a serial port and tmo.

A lot of people use pocket loggers. You can also use a Test light or volt meter. Browse the vfaqs I forget the category it's under though.


2g awd, Back to dsms here I come.

You can easily test for codes with a cheap analog volt meter just connect the leads pin 1 and pin 12 of the diagnosic connector. it is the white connector right beside you drivers side fuse box. Then you turn the key on and count the sweeps of the needle. The long sweeps count as 10 and the short ones count as 1 ie 1 long sweep+ 1 short sweep = 11 which is a O2 sensor code but could still mean other things like injectors, Air leaks, fuel pressure. the code only gives you a place to start looking doesnt mean it is for sure just an O2 sensor issue.

DSMer here, no link smile

Sounds like the coil pack or power transistor (ignitor) took a dump.

A Haynes manual will tell you how to read your OBDI codes. Also http://www.vfaq.com

So I checked the codes with the volt meter it looks to be number 23 Cam position sensor. Dose that sound right for the problem I am having. I never had to deal with problems with the 92 tsi I used to have owned it for years never let me down. Are the Cam position sensor known to go south on DSM's?

Ya its common for any car that age to have sensors, especially moving ones, start to fail. The repeated heat cycles, break the outer seal over time. Any moisture inside can cause the sensor to fail. Some have taken them apart and cleaned them with success, others not so much. Personally Ive never been able to get one to work again after it got pooched.

Simple fix. Make sure you use a timing light when you replace it to get the base timing set properly or bring it to a mechanic to set it.

Now the code is saying Camshaft position sensor but my repair book is showing it as a crankshaft position sensor in the litle picture. Are they in a diffrent spot on the 93-94. Correct me if im wrong its the roundish part on the end of the intake cam?

Cam and Crank sensor are both the same unit at the end of the intake cam. It uses the crank sensor to control the fuel injectors and the cam sensor to control ignition coils.

Correct, it wasnt untill 95 that the crank sensor was a separate unit attached to the block in the crank sprocket area. Previously, the two sensors were one unit at the end of the intake cam. I think. Im a little grey on the configuration of late 1g's, but I think the cam sensor at the end of the intake cam shaft is your culprit.

Yes because in 95 they switched to OBDII so they needed to be able to measure crankshaft accelleration to give you misfire codes
