Is this the answer to my hisitation and cutting out problems???

I have an '87 944S with a bad habit of cutting out. When it does this the tach will drop to zero and then the engine bounces back to life. Other times it will just die and other times it just hesitates. The plug wires don't arc and I don't get a shock when I touch them so I assume they are ok. I've replaced the fuel filter, pressure regulator, cap, rotor, coil, ignition control module and even cracked open the DME (which was fine.) This morning while at idle the car was cutting out. I opened the hood and heard a click from the ignition wire from the coil to the cap. Everytime it would click the engine would cut out. I touched the wire boot at the cap and got a nice shock. I touched the wire in the middle and got an even nicer shock. Could this be the answer to my problems? Thanks for any ideas.

That is most definately the answer

Replace the wire, check the coil for evidence of damage or if it is leaking

me too?

Hello,

I am having the same symptoms it sounds like. Hesitation, or cutting out sometime. I have not checked the plug wires, etc. But I know they were all replaced recently. I am wondering if I could be having the same problem. I am a complete newbie though so I am attaching a picture to try and make sure I understood what wire to check/replace. Also, did it fix your problem flormat?



also a few more pics for reference:

That is a correct wire, but fom you pics I would check out your AFM it looks like it has been resealed, maybe someone has played with it

MAX29a:

You should also take the slack out of your throttle cable. You have an aftermarket throttle response cam, with what looks to be about an extra inch of slack in the cable. You might have to take some of it out at the gas pedal. The rest can be done with the adjuster under the hood by the firewall.

This wont fix your hesitation or cutting out, but it will improve it a little bit.

Thanks for the notes guys. I hoped I might get some more comments on stuff to look at if I posted a big pic of my engine bay. I definitely noticed the slack in the throttle but I didn't see how to adjust that.

I just got my Haynes manual recently. Is it in there?

Also, whats an AFM?

air flow meter - it's the metal piece that connects to the air box. (to the right of your distributer cap and just behind the hood latch). This sets the amount of air the engine gets. This sensor often goes bad and needs replaced along with the O2 sensor. I'd reommend doing the O2 sensor first as it's only $30 and easy to replace as well. The AFM can be fixed. Go here and click on the AFM button:

I, personally have not found a replacement AFm that works well yet. I'm going with a new one this time, but it's about $500 for a new one.
