2002 Rough idle/misfire

Hey yall. I have a real headache here that I could really use some help with. My girlfriend has a 2002 Xterra 3.3 non S/C with 113,000 miles on it. This problem has her convinced the car is garbage and she wants to sell it. Please help me fix it so she'll keep it!

It has a rough idle. When the car is in Drive the car will shake rather violently when stopped. It will occasionally clear itself up and start idling smooth again for about 20 seconds and then go back to shaking.

When driving, it will drive fine for a while but after getting warmed up it will has periods of nearly total power loss. For example she'll be driving on the highway doing 60mph and it will begin to "misfire" and the car will slow down to about 40mph. Usually during this time, the SES light is blinking. She pegs the throttle and it won't accelerate... total lack of power. This will last for a minute or a bit longer, then the car will go back to normal. It has yet to stall completely.

The car has these codes:
Multiple cylinder misfire/Random
Knock Sensor
Running too rich/lean (it alternates (i think?... i didnt pay excellent attention last time I had a scanner on it))

Since the problem began I have done the following: (ive been reading the forums and trying everything I read about)
Replaced spark plugs and wires (they are gapped to .43)
Replaced entire distributor (had rusty debris around the bearing)
Replaced timing belt (It was loose and making noise)
Replaced fuel filter.

(I can take the wires off any cylinder and it still shakes the same. No difference. Whatever it is, is affecting the whole engine)

I kept getting told it sounded like an ignition problem, so I replaced the entire ignition system (except the computer?).
All that I can think of now is fuel, which I started with the fuel filter. I wanted to hear from you guys before attempting the pump/sending unit.

The car acts now EXACTLY as it did before I did any of these repairs, so I highly doubt I used a bad part or did anything wrong.

Last year a friend replaced the valve cover gaskets.

Thats all i got yall. Please, any light you can shed on this issue is much appreciated. Thanks in advance!

Try the MAF sensor, it might need cleaning.

If the timing belt had jumped a tooth, etc, when you changed it, it might not have corrected it if you didn't reclock, etc.

Did you change the tension pin, etc, and water pump when you did the timing belt?

You didn't mention an air filter change?

I will clean the MAF sensor now.

The timing belt was done by a local mechanic who I trust, so Im assuming it is clocked right. Kindda a tough one to second guess though, it's a lot of work to check as you know.

When I had the belt changed, I was on a real budget so I didn't change anything else. I was just trying to correct the fault.

The air filter is clean enough. Certainly not clogged or moldy or anything.

I assumed the timing belt being jumped would indicate a loss of power constantly, not the intermittent issues I'm getting? Am I right or should I seriously consider the belt again?

Did you guys have any resolution to your issue(s)? Having similar. Tune-up was about 50k ago (she has 171k on her) and we just did a fuel injector service thinking it might be a bad tank of gas (I threw in some dry gas as well). I'll clean the MAF next since a lot of research seems to point that direction.

Exact same problem but worse, no power the majority time I'm driving, up hill slows to a crawl (10mph or less), even hills that are not steep at all... from a complete stop it crawls up with a lot of struggle and my RPM's shoot up and drop with no change in gear (automatic) regardless of the fact Im not applying my foot to the accelerator. If I can get it up to speed for the intersate (usually cannot) then I have to maintain steady pressure to the gas or I will loose all power and slow dangerously down. Ive been told to replace all the things Hamm3r has replaced, but have only done distributor cap, spark plugs, oil filter... I will check MAF next.
I need help!

I bought a 2000 Nissan Xterra
For $2000, that has 2000 problems...

I would next take it to good muffler shop and have a flow test done to see if the cats are plugged up.

Make sure there are no vacuum leaks, clean the MAF, check your timing, make sure all plugs and wires are attached properly, make sure all your grounds are connected properly (on top of the intake manifold), check to make sure you have the correct distributor, check electrical connections for any green corrosion or improper connection and clean if necessary,

If all of that checks out, I would do a compression test. Are you losing any oil/coolant?

Hey Thanks guys,
Ok, I will see about the flow test, have not gotten a chance to look up how to clean (or identify my) MAF yet, I'm not very knowledgeable so I have to look everything up as I go...
For example not sure how to check for vac leaks myself, or most of the other things listed by awesomekasim...(I can check for corrosion, but I haven't spotted any yet and Ive climbed all over the engine just trying to understand where things are). Though I really really appreciate yall pointing me in the right direction!
I haven't noticed any oil in the driveway, but I have to refill my AC (is that the same as coolant?) quite often. However one time I added freon and it ran a little better, this last time (3 days ago) i noticed no change so I assumed it was a fluke. Still sluggish, laborious and dangerous to drive on interstate, which I have to do 5x a week for work in order to afford the parts and work...

Might be worth mentioning... it has 155,851 Miles on it, had 145,000 when purchased and told needed a "tune up."
