Why doesn't anyone give some legitimate fixes on here? Just complaining about it won't help anyone.

All cars have problems, otherwise dealers wouldn't be in business. Come back and let everyone know what fixed the problem.

OK, here it goes. I have a 2002 Nissan Sentra GXE 1.8 with a manual transmission, 116000, and other than typical preventive maintenance, the car has been up to now pretty reliable.

However, I now have a high idle problem with originally no Check Engine Light (no codes). This happened after starting the car upon returning from a six day vacation. BTW I was trying to get this car to Hartford to give to my brother, because his Dodge Intrepid with the crappy 2.7 engine bit the dust. So I hesitantly took it to the dealer for hopefully a quick fix. They have $1000 of dollars of all that fancy equipment to work with, so I thought they could get the job done. Right? Nope! Never again will I take my car to a dealer for any maintenance whatsoever. This is what they did.

They removed the duct between the filter box and throttle body. Sprayed some carb cleaner and charged me 175 beaners. Decarbonization they called it. Ha ha sucker. What a joke. They said "Come on back tomorrow and we will replace the IACV and you'll be good as gold". Sorry pal, no thanks. So, I took the throttle body off, cleaned the back side of the butterfly, which was still dirty. Removed and cleaned the IACV and reinstalled.

Still no good. Now what? Borrowed a scanner, which showed an erratic TPS angle reading. Replaced the TPS. Still no good. Had been idling at 2200 RPM, then below 15MPH starting fluctuating between 1600 and 1750. Now is idling high, but not coming down. A lot of these little sensors can get expensive, besides looking at replacing the ECM. Which I guess I will have to start pricing. But I am going to check all grounds first. Will let you know soon.

Hey, please let me know if you've got the fix for this?

I have a Nissan Sentra GXE 2002. It has 75k miles on it. Within the first month of buying it, I am getting the stalling problem on signals and at very low speed.

Before two days, it got worse. I was not able to start the car even. After half an hour, it has been started. And it is running fine right now. It gets the stalling problem a few times in a week. Need to fix before it gets worse.

Can anyone suggest to me what could be the fix?

Hi Guys.

I just got my engine light on last month, and changed the crankshaft position sensor. Car is not having any stalling issue since a month. Hope I won't get any problems in the future.

Hello, I have the same vehicle. I'm a licensed tech. I found that my problem, which is very similar to yours, ended up being a fuel pressure regulator; a fifty dollar part.

Here's how to troubleshoot when the vehicle is acting up. Pinch the fuel return line. If the idle goes back to normal, your regulator is probably stuck open. But the proper procedure is to hook up a fuel pressure gauge.

Hope this helps. Send me an email if you have any more questions. aelalonde@hotmail.com
