Drivetrain Throw-out Bearing.. Check Engine Light?

oneslowgt · Sep 19, 2013

So my throw out bearing is bad on my 95 cobra, and when im driving after about 3 minutes a check engine light comes on.. but it goes away after re-starting the car. Do these have any connection? I took the car to autozone to get an OBD but the obd reader wasn't reading anything it was saying error?

anyways im looking for an OE replacement for throw out bearing is there a guide out there that anyone knows of and also what product should I buy I was looking at http://www.latemodelrestoration.com...L-Ram-Oe-Replacement-Clutch-Kit-105-10-Spline is this the right one for my car?

There's no connection between the TOB and the check-engine light. The Autozone OBD-II reader won't read our OBD-I cars. You can get a special scanner or you can jumper pins on the test-port (behind the passenger strut-tower in the engine bay) to have it flash the codes on the check-engine light (you can find instructions searching this site and others). The port inside the car was only used on the V6's so you'll get an error hooking up the usual scantool.

For a stock replacement I'm a big fan of the King Cobra (genuine Valeo branded) clutch. Lighter-than-stock pedal, smooth engagement, but tons more holding power (600hp). Available pretty cheap too on eBay (UPR Products carries the proper non-knockoff version -- be careful elsewhere).

As for how to keep the TOB from wearing out again -- do you have the stock quadrant / self-adjuster or an aftermarket unit? The stock adjuster (and an improperly adjusted aftermarket one) will both put the TOB in constant contact with the pressure plate. That's why people recommend the OEM TOB only, and why even then you're lucky if it doesn't start making noise within 25k miles. imho the best way to remedy that is by using an aftermarket adjuster, and leaving a proper 1/8" of slack ensuring the TOB is away from the pressure plate when the pedal is released. You'll also want a return spring to pull the fork away from the pressure plate to guarantee the clearance is kept and to minimize chirping.

so i bought this tool and the check eng light pops up after 2 min of driving but goes away if i turn off the motor how do i get the code? where is rhe plug in

If you got the correct scantool (probably looks like this):
http://contentinfo.autozone.com/znetcs/product-info/en/US/acm/CP9015/image/3/

Follow the instructions in the booklet that came with it to do a KOEO (Key-on Engine-off) test. As I mentioned the harness is behind the passenger strut tower under a plastic cover. Any codes that were captured while running, even intermittent ones, will be stored and flashed / beeped out after the KOEO test finishes. It first beeps out any codes that are current (bad sensors, etc.), then a separator, and then any stored codes that might have been intermittent. It it lit up your CEL, it's there for you to read.

Another good, cheap scan tool for EEC-IV mustangs. I recommend the extension cable, but not required

Can't argue with that, I hate counting beeps. I just assumed the Op had one like that pictured since he mentioned Autozone and stated he'd already picked one up.

ended up with code 33 i think it will be fixed maybe with a little maf cleaner on the egr valve maybe its sticking

There are no 2 digit codes from an OBDI system. Counting flashes?

im pretty sure your wrong but ok lol the booklet i got with the code reader has 2 digit codes

jozsefsz · Sep 27, 2013

The '95 is going to beep out 3 digit codes. The beep-beep-beep pause beep-beep-beep is a '111' repeated twice. That means no issue found.

Is this the code reader? I'm wondering if you have an older reader from before 1994.

Your post above is completely correct -- the EEC-IV through 1993 uses 2-digit codes. The 94-95 use 3-digit codes. It's possible that someone retrofitted a Fox computer in the op's vehicle, but unlikely since it's a Cobra (which has a different MAF map).

Just to clarify, even if the op picked up a pre-1994 reader (which would likely not be digital since he's counting beeps and would also be unlikely to find one that old on a shelf anywhere) it would still work even if the booklet doesn't contain the 3-digit codes.

I don't think there's any big mystery here. He's seeing 1-1-1 repeated twice. The computer always beeps out the code twice. If he was seeing '33' for real, it would be 3 beeps, short pause, 3 beeps, long pause, 3 beeps, short pause, 3 beeps. He said he's seeing 3 beeps, pause, 3 beeps. That means 1-1-1 being misinterpreted (which isn't hard to do).

you sure its a beep beep and not a meep meep?

That's hilarious. Reminds me of that Spongebob episode where he thinks Mr. Krabs is a robot. (I have kids so I have an excuse).

Your post above is completely correct -- the EEC-IV through 1993 uses 2-digit codes. The 94-95 use 3-digit codes. It's possible that someone retrofitted a Fox computer in the op's vehicle, but unlikely since it's a Cobra (which has a different MAF map).

Just to clarify, even if the op picked up a pre-1994 reader (which would likely not be digital since he's counting beeps and would also be unlikely to find one that old on a shelf anywhere) it would still work even if the booklet doesn't contain the 3-digit codes.

I don't think there's any big mystery here. He's seeing 1-1-1 repeated twice. The computer always beeps out the code twice. If he was seeing '33' for real, it would be 3 beeps, short pause, 3 beeps, long pause, 3 beeps, short pause, 3 beeps. He said he's seeing 3 beeps, pause, 3 beeps. That means 1-1-1 being misinterpreted (which isn't hard to do).

i think you are right about the 3 digit codes. But what I noticed is that it beeps along with the abs light flashing but the check engine light does not flash!! and the check engine light only pops up while driving and goes away. HOW can i get that code??? and how do I do the thing where the check engine light flashes the codes at me

Believe me they are three digit codes. Here's a link on how to read the codes without a code reader. For $22 I would buy buy a reader . You are testing at the correct DTC (Data Trouble Code) port aren't you? It's the one between the passenger strut tower and firewall. It is NOT the one under the dash nor the one next to the engine fuse box which is for the ABS module. The ECU (computer) stores the codes and a code may not cause the CEL to flash. If the ABS light is flashing you have an issue with that system and that has nothing to do with the DTC's
