1999 Nissan Maxima SE idle problem

After the engine warms up, the car's computer lowers the rev's. When this happens, the car starts to "bounce" around 600rpm. It causes vibration and could become a big problem in the future. If anyone can help me diagnose my car, I will be very much obliged. Also, there is no check engine light on, so I can't diagnose that way.

dude i got a similar prob. on my 1999 GLE maxima but mine stalls out in reverse and sometimes while im driving if i let off the gas sometimes. I had my friends dad check it out and he said he thinks its a vacum leak. I still havent got around to getting it checked out but you should look into that cause my car has the same idle prob. too

to check for vacuum leaks, u spray starting fluid over the engine. if the rpm's jump that means u have a vacuum leak. i did this, and i didnt find any leaks.

I figured that the wire was lose because I may have pulled on it during the cleaning. Anyways I cleared the ECU and drove it about 200 miles so far. No Check Engine light yet. :( I was so happy when it came up, because I thought I would be able to diagnose the problem. Figures, it was a fluke.

ok. so now a check engine light came up. it's for an oxygen sensor. bank 1 sensor 1....codes p0134 and p0171. I took off the oxygen sensor and inspected it. It looked fine. I had replaced it earlier with a new one, and so I double checked to make sure I didn't mix it up with my other nissans. Sure enough, all oxygen sensors had been replaced. I reinstalled the oxygen sensor, because replacement would have been unnecessary.

ok guys, i cleaned the IACV and while I was in the area I cleaned the EGR valve. Still no luck :( but I did notice a little more power. MAF cleaning is on the to do list. If anyone else figures out how to fix this problem, let me know. Thanks

Check the MAF (Mass airflow sensor), it may need cleaning.

[thegreat1dev]

thanks. i will do that.

I have a 92 maxima that had a similar problem. Check your idle air adjusting unit as a screw likes to fall out of it causing the idle to get all messed up and causes the car to stall frequently.

I think you made this video just to showcase what faggy music you listen to.

Get in there and clean out your throttle body, IAC and MAF.

I had a simular problem on my 01 SE Maxima . I had to repair the ECU, replace the IAC, TPS, and MAF. You can look on ebay their is a guy that can repair the ECU for $200 with a life time warrenty. I haven't had any problems since.

You ever figure out what it was?

I had the same problem... at red lights it would vibrate and stall, but if I was accelerating it'd be find. It was the EGR valve. I was stuck shut and had to be replaced.

Clean your intake system, but more importantly Idler Air Control Valve.
