Who is this guy???

 

Perhaps somebody that would like to protect the reputation of their company...................

 

You can't just make a statement like that without being a little more specific. Is this your opinion or do you have some insight?

 

The obdII scanner should read a P0300 misfire detected but would also have a check engine lite. I also had another one with a head problem today[sm=boohoo.gif]

 

H3X442: I hooked my OBDII scanner up this weekend and have absolutely no errors, BUT whenever I come to a stop and take it out of gear, as I'm approaching the stop my idle dips below 500 RPMS until I come to a complete stop, then it boosts back up to normal, around 750 to 800. It was happening almost every single time I stopped from maybe Tuesday or Wednesday until yesterday. Today it didn't seem to do it, but it's 31 degrees as opposed to last week when it was below zero most of the time I drove it.

Have you ever seen that before? Does the head and valve problem definitely produce an error code?

 

Mikey...It sounds to me like the Clutch switch maybe acting up..Look at the connections to the switch that's actuatated by the clutch pedal (near the clutch pedal under the dash)...I had an RX7 that would do exactly as you described and I found the clutch switch faulty....Disconnect the plug from the switch..Take an Ohmmeter and check out the switch, press and release the pedal and see if the switch opens or closes consistantly...

 

That's what I thought also. I actually removed the clutch sensor plug you are talking about on Saturday because I was wiring a remote control switch for the KITT lights and had some of the wiring going through the harness, and thought, ok I'm going to plug and unplug it a few times to clean it.

I haven't noticed it happen since, but I'm wondering A) is it possibly the cold weather doing it and B) wouldn't the PCM get an error code if the clutch sensor was faulty C) perhaps the + source wire that was going through the wires on the clutch sensor was causing some EMI in the sensor which was giving the PCM some bad signals. That + is coming from the infamous AUX B+ wire behind the console. That produces alot of power since it's tied right to the battery.

Since I did that the weather has gone from about 5 degrees to the now 31 degrees this morning. It also started once they changed the surpentine built and belt tensioner pully. It was doing it when I got the car back from service that night but that was also 2 days after I installed the KITT lights and ran that B+ wire tap. There are bunch of variables, but I'm going to remove and replug that connector a couple more times before I leave work today and see if it does it anymore. That may just be it. Thanks buddy

 

My RX7 didn't throw a code either..The dealer at the time (Kenny Kent in Evansville, IN) couldn't find the problem although they agreed there was a problem...Anyways..I started with the common element as it only happened once I pressed in the clutch when coming to a stop...Most the times the idle would dip so far and the car would almost stall, it did stallwhen the A/C was on...

Spray some contact cleaner on the switch and the connector. (Deoxit is great)

 

I haven't seen contact cleaner is ages since Radio Shack stopped carrying it. Do they sell that at regular auto stores or do I have to go to a electronics store to buy it?

That's exactly what it's doing FYI.

 

Go to an electronics parts house...Radio **** don't have crap anymore..all they want to do is sell you a Sprint phone service...
