How old are your wires? Like I said above, if they are over 5 years old, chances are they may be bad. I know they aren't cheap, but they are the next thing to change. Generally you can't see or feel if they start to deteriorate. I would have done the cap, wires and plugs at the same time to save labor time. Now you have to go in there one more time disconnecting and reconnecting them on both ends. :D

There is a good chance that they are over 5 years old, I have had the car for 4 years..

I will be ordering some up Monday thanks for your help..

Beru ignition cables will make any 911 ignition challenged. Add rain and the situation becomes magnified.

Should I buy Beru,Magnacor,Bosch or Clewetts and are Magnacor and Clewetts the same brand because,Clewetts Website sells both?

Just make sure they're carbon core and not stranded copper.

89cab, make sure you save all the parts you replaced up to now. If your problem turns out to be different than ignition-related, you will have a stock of known, good used parts that you can use to diagnose future problems....without having to throw money at it.

Many people here like the Magnacore, BTW....the Clewetts have a good reputation as well.

Noted,Thank you

Also, you might consider sealing your distributor cap at the perimeter where it meets the distributor with Ultra Grey sealant to prevent moisture ( whenever it rains ) from getting inside and causing your problem in the first place.

Another problem area are the rubber boots on the distributor terminals that have a tendency to wick water when wet causing shorts on the cap.

OK,just installed new Magnacor wires,and I have to say removing the old wires was a *****..
there was a fastner under my A/C compressor that I could not get to, in order to remove the old Beru wires,so I had to cut them out,the left side was easy but right sucked..I can feel a big differance it seems like more power, WOW!!! Hasn't rain enough to tell if that was the problem,but I am glad I got to replace them..

AC compressor is easy to unbolt and get out of the way, I usually get it loose when fishing the ig. wires in/out of there. Is it your opinion that the new wires fixed the problem? Is it running smooth now?

If it gives you problems again "post 19" I just had a speed sensor puke out finally after chasing an intermittent problem. A quick test will tell but only if it is bad when you check it.

Congrats on your fix, just a silly question but when you reconnected the old Beru's did you feel a "Click" when caps were replaced on those new plugs?

I replaced my Beru's too but when installing my Magnacor's I realized one did not click on causing my rough performance.

Here is the thread I referenced back on post 19 concerning the problem with my sensors. Keep it in mind if you are still experiencing problems.

Yes I did,that kind of worried me they are not a tight fit on the plug side...

Thanks MH911:D

Nice thread, I am with you every time I do a search no one finishes there thread to tell us what the results are from there repairs..I know most people get excited when fixing the problem and feel that it may not help,BUT IT DOES!

Also my next step if the problem returns is to replace the sensors..

MH911 Do you have a good and reasonable mobile Mechanic ,I live in San Jose..Thanks
