Need help!

[NMWBT]

I have a stock 2000 GTP with 195k miles. It has been running great until recently. When cruising it hesitates and bucks. It is more noticeable when climbing small hills, when the engine is under load. I changed the plugs and wires but didn't help. I also cleaned the MAF which didn't help either. I have an Engine Light on and had Autozone pull the codes. They were P0135, P0102, and P0443. Any ideas??

The P0443 code translates to: "Evaporative Emission Control System Purge Control Valve Circuit". To find more information on this code, go here: http://www.obd-codes.com/p0443 For a complete list of codes, go here: http://www.obd-codes.com/trouble_codes/

P0135 Oxy sensor
P0102, MAF

I'd start with 102 it's easiest to change then its a crap shoot after that

In my experience, if I have P0102, it's a bad MAF. Cleaning has rarely been enough to get the MAF working properly again. Try unplugging the MAF, driving around, and seeing if the problem goes away.

http://www.obd-codes.com/p0102 this one is the maf code check the wires to the plug for the maf if you see cracks thats the problem.

http://www.obd-codes.com/p0443 evap purge solenoid maybe, read that.

http://www.obd-codes.com/p0135 o2 heater circuit. all this means is the o2 heater quit working the o2 is stil working tho.

the first one is your immediate problem.

I was also getting these same codes and it was a blown fuse in the under hood box. Fuse #21 I believe
