94 SHO MTX problem!

[kartmonkey9]

I have a 94 MTX that just started acting up. Ill just be driving and when it gets to the point where its warmed up, i will loose my tach, so my rpms just die, and my check engine light will come on and my motor will stutter, sort of like its starving for fuel or something. At first when this started happening, id just shut it off and start it back up and it would run fine again. But now its to the point where it would just die randomly while driving and then start hard. Im thinking cam position sensor for my first guess. Let me know what you think..thanks

I would guess more along the line of a defective VSS.

 

[kartmonkey9]

Would that cause the motor to die too?

 

[SASHO91]

Sounds like a CID to me as well.

I'm thinking Crank sensor

I would start with the CRANK, then CAM sensor.

KYLE! lol i have riddin in this car when this problem occurs seems to only happen in 5th gear at cruising speeds. The whole car jumps jerks hard like the tranny is breaking then the tack dies and sometimes the car well die too. we have yet to pull the codes on this car but kyle has plenty of time seeing how he has no license i was leaning towards crank sensor or VSS...what do you guys think?

 

[yamahaSHO]

Why the Vehicle Speed Sensor? You can run fine without it.

 

[Ishodu]

Rather than guess why not run the codes?

Guessing is funner.

Crank sensor.

ill pull the codes for him tommorow and see what comes up!

 

[kartmonkey9]

Hey pulled the codes got a 157, 214 what cha this, it has a brand new dis and coil pack, the other code is for a low maf or some shit and bad ground?

 

[kartmonkey9]

"bump"

 

[93rev2sev]

Have you replaced the crank sensor yet?

the only other thing I can think of is a dirty(as ****) MAF sensor. But I'll bet you one dollar it's the crank sensor.

 

[bigred56k]

Well do

 

[GreenShoOwner]

Dirty air filter? lol, ok sorry. (I do love it when it's that easy though.)

 

[SHOMON]

That 214 code is the cam sensor code. trust me, my cam seal is leaking on my 95 atx and that is the only code I get.

 

[bigred56k]

Okay guys did the cam sensor...still is effed up..only seems to run bad at operating temperature. I have reason to believe that its the water pump dripping down on to the crank sensor when the car gets warm then causing it to short out????? If i sit there with when its running bad and hold the throttle at about 3000 rpm's the tach on the inside of the car well jump all around the place?

what cha think should i do a pump and sensor??

You can lead a horse to water but you can't make him drink...

I would start with the CRANK, then CAM sensor.

Well do
