04 maxima sl has no power/won't rev past 2500 rpm
 

Hey guys, I'm having a problem with my 04 maxima. About a month ago i was driving home from work when my car suddenly lost power and i had to tow it. It still runs but if i give it full throttle it starts to bog down almost instantly and if i ease into the throttle it will rev to about 2500 rpm before it starts bogging down. I had 2 codes for the camshaft position sensors so i replaced them. The car was still doing the same thing so i checked plugs and coil packs. The plugs were pretty worn and one coil pack had been arcing through the side of the boot so i replaced all 6 plugs and coils. I'm still having the same problem. I'm at a loss for what the issue could be so i thought i would seek the advice of the forum before i got a mechanic involved in the issue. The car has right at 130k miles and is an automatic. Any other info you guys need just lmk and I'll be more than happy to provide it.

Codes would be nice.

Point taken. Post deleted as they had no bearing on this issue.

i can't remember the exact numbers for the original codes but it was bank one and bank 2 camshaft position sensors. I replaced them, cleared the code, ran the car and got the code for random cylinder misfire. I replaced the plugs and coils and cleared the code again and i haven't had one show up yet. All i can do though is let it idle because it doesn't have the power to drive. It tries to shut off.

Multiple issues/sensors/systems can be related to one code. I haven't seen a work flow in my 5.5gen FSM that lists only one sensor or system. Let us know when they come back. Until then, there's not much I'm going to say. It's obviously in limp mode and I have a hunch it's your CKP, but I don't speculate with too little info like most people do.

Have your mechanic drop the exhaust before the cats or pull out the pre-cat O2 sensors then try it.. Many times plugged cat will cause these issues and lead you on a merry chase.
