can i get some help for once?

[DEMONICSHO]

ive asked about 20 questions and i think ive gotten two descent answers that i could use. here it goes one more time,when i unplugg my cid sensor after the car warms up i lose tach readings from the tachometer is this normal or is it not? the reason i am asking is in messing around trying to locate my problem i unplug it and lose all tachometer readings. ive done this three times with the same loss of reading. i unplugged it the other day and i still had a tach reading. i also checked on the alldat site and it says cps is what gives the tach readings, but ive heard on this site that it is the cid sensor, i also get a hard start nearly everytime i try to start the car. has there ever been a case of a bad cps that caused drivability symptoms. before you answer i know if the cps is totally bad you get no spark.

When you unplug the cid the tach should be inop. The sensor is about $35 and it will cause hard start if it is failing, and you ask how I know this is what my 93 did when the cid was failing it will still start but it will be in limp mode. If my answer is not to your liking then DONT LISTEN TO IT!!

With an attitude like that, and these false claims, its amaizing anyone is willing to help.

You have started but 7 threads, including this one. ALL of which were responded to, and questions answered.

Moreso, every one of these (with possible exception to the fuel pump) topics has been discussed before. And can be found using the search function.

lol, not so slow... FTW!!

so like i said the last time i unplugged the tach worked, is that odd? why would that happen? and as long as i get your guys attention ive accomplished something. wether or not you want to take it to heart, thats your decision.

The CPS drives the tach. Not the CID. The CID works in conjunction with the CPS to give a signal for proper fuel & spark timing. The CID has no relation to the tach. If the tach drops out and the car is still running, I'd look at a electrical problem unrelated to the engine controls.

Stop unplugging sensors, that's your answer!

 

[sdpatt]

A faulty CID (cylinder identification sensor, camshaft position sensor) can cause the engine to stumble if it happens during driving. If it faults during a start, the Check Engine (CE) light will not go off and the engine may backfire or stop spinning with the key turned to start. A good explanation may be found in this forum regarding the contribution of both the CID and CPS sensors to the tachometer signal from the DIS.

He who asks kindly will be responded to the same. He who spits in the wind will deface only himself. The Forum is a valuable resource. Treat it like one.

Amen Brother Scott!

******* in the wind has the same effect. only you get more wet.

And it makes you stink

Wow,...good information on two counts. Those sensors are good to know about and I'll be sure never to irritate anyone on this site!!!!!

Hey, I appreciate the info. I'm 51 and old enough to know that you're never too old to learn something new. I love this site and it is great resource of people with practical experience.

Here's an ARMY one for you...when you "assume" you make an ASS out of U and ME....

Later guys,...nice cat fight there!

 

[Toolman]

I do not see a cat fight, only someone being taught a vital life lesson.

 

[TROG]

righty right, what what...carry on lads....good SHO!

Do a search for "testing the DIS". With a DMM (digital multi-meter) and an LED test light (NOT AN INCANDESCENT TEST LIGHT) you can test the CPS, CID, coil power, etc. The tests are simple and easy to do, and will assist in diagnosing the probelm. Start by clearing the fault codes and then run the engine and check for fault codes.
Keep in mind that a fault code does not mean a sensor is bad. It means that the programmed signal is not getting to the CPU. The reason could be a bad sensor, say the CID, or it could be a bad connection, such as a loose connection or one that is corroded. The problem could also be a shorted wire, or an open in a wire to the sensor. Lastly, the problem could be a bad ground. If you are not happy with the responses to your questions here then try another forum.

well thank you to those of you that helped, the stop unplugging the sensors was the stupidest post ive ever seen, but besides that thanks and my apologies for the post. im beginning a check with the wires to the cid sensor. i noticed there is a wire wrapped in a heat shield or aluminum of some kind? this travels up the cid sensor harness. is this a ground? there are some portions of it that are unwrapped slightly.

You are confusing the sensors with each other. The CID is the CAMshaft identification sensor, located on the rear exhaust camshaft, near the firewall. The CPS, CPK is the CRANK position sensor, located on the oil pump and behind the toothed sprocket that drives the timing belt. The wire you speak of (the one wrapped in the alum heat shield) is coming from the CPS, as the CID has no wires (the wiring harness plugs directly into the CID).

And you have to be the stupidest newbie I've ever seen.

You come on here posting a thread asking for help but feel the need to be a combative a-hole about it, and you expect all peaches and cream replies?

Adjust your attitude or take a hike. Thread closed.
