Hi there, I have a
2001 Nissan Altima GXE Limited Edition 2.4L (automatic) 136,034mi.
I've been having problems for a while now that I can't figure out. Also, when it comes to mechanical problems (and I mean ONLY mechanical, not electrical or computer programming) I prefer to do things myself if at all possible in my shitty apartment complex.
Anyways, the main issue I have is my idle.
ONLY when the engine is nice and warm do these problems occur. 2/3 problems are infrequent, but on a regular basis:
1. IDLE: (constant) my idle is really messed up. (With AC running) in park I currently have my idle set to 1500 RPMs to circumvent this issue as a temporary fix. My idle erratically dips (and periodically) rises when I'm not driving (fir example at a stop light). If I'm running the AC (not just the blower) the dips can be as extreme as a 700 rpm drop. With the adjusted idle, while in drive my RPM's are at 1000, and periodically dip to about 800. Infrequently, (using when I start driving) my idle will increase by about 500-1000 for seemingly no reason at all.
Then, while in drive, my idle gets stuck (and continues to act erratically) ONLY between 39-50mph. If I drive at 51mph or higher there are absolutely no issues at all.
2: ERROR CODES (infrequent) I'm pretty sure I have to replace my catalytic converter. Every week I receive (and clear) a bank 1 P0420 error code. What's puzzling though is sometimes it's clear for 5min, 1 hr, a day, a few days, or even a week before coming back on. In theory, after clearing the code (and assuming my cat is in fairly bad shape at this point) I should get the error code back every time I start driving after clearing it.
Finally, (very infrequently) I also receive a P03? Cylinder 1 Misfire code reading. It might occur once in a week or two, or sometimes only once in a month.
I have replaced:
My Air Filter (multiple times, with varying brands)
My Throttle Position Sensor (TPS) based on a recommendation from a few people.
Also had my oil change done
At this point, mainly due to inconsistency with the error codes, I'm wondering if anyone has an idea what's wrong with my 2001 Nissan Altima GXE Limited Edition 2.4L (automatic)..???
Thanks in advance.
