Truly i'd say that its hard to belive that its normal idle for these cars becose the engine shakes too much, and also when i turn A/C on ...oh man it shakes all inside and even my rear passengers on the back seats really feel that...

Furthermore my brother in low had a same car and i was driving it and i can say it was a big difference and it had idle about 800-900 RPM
And also i got diagnostics at the shop and they found out that crankshaft position sensor ...

so...

well mine purrs at between 375 and 500 smoothly. Maybe the earlier models are a little different. I drive a 2000. Had my sensor replaced also but didn't have any early warning symptoms. It just died, cruising along. No engine light... nothing!

You know what? I'd say that it's not normal,you know,it's not normal.I really don't like this. If the engine has so low RPMs it means that it has hard capacity on it,espesially when you turn on A/C,the ligths, the radio and something else...you know what i mean don't you? Thats no good for ur engine... But i'm not gona live it this way,you know. I wonna find the problem and i hope i will. i gonna replace as much parts as i can to find out what's going on with my car.I'll be work on it. i'll tell you how much i'll got done and what i did for that. I'm going to replace DIS-module tomorrow and after that we'll see...

The bonus question: There is hose dangling that is not connected to anything. I have the same thing now after changing my sensor. (The car just stopped running on the highway was my symptom. I got a code reader and it said bad sensor). Where did that hose go? I can't find anything to connect it to.

It depens on wthat kind of hose you found. I found a black hose and it was not connected to anything .I spent mine time to find what's going on but i couln't find anything. I asked another people and you know what? I found out that it was no problem. This hose just needs to be disconnected because it's like pressure line for the ATF fluid and it goes from the top of the tranny. So it all good in there and i don't worry about this anymore

I was hoping it was some kind of atmosphere vent. I sprayed some carb cleaner around the area to see if it raised the idle (a standard vacuum leak check) and there was no change.

I cleaned my injectors in a shop. They didn’t take them of they just put like an av thing inside and put chemicals in there to clean it up, but after that nothing changed...

I had the same symptoms - the car would start and run perfectly, then die while driving, or fail to start on several long cranks, then kick right over. It was the CPS. I had the car at my local mechanic for a week and he couldn't figure out what was wrong. I checked this forum and then my dealer replaced after I told them what it was.

it's a major and totally incompacitating inconvenience.

Perfect symptom description...Perfect connector and CPS location pix....Found sensor at a local in-stock Mom-and-Pop parts place for $45...Auto=Zone and Murray's were both $85....ALSO...Murrays loaned me the "Mac Tool? to diagnose the problem throught he OBD2 connector..for FREE...
Thanx Agian....Problem fixed for less than $50..Not including the $150 towing...
Final Comment....Why in the world was the "Check Engine" light not programed to illuminate?
