Just a couple of thoughts on the codes. You might try checking your gascap and evap canister hoses for the PO443 and for the PO135 check to make sure your O2 sensor wires are ok. Thats an O2 heater malfunction so it could be the O2 sensor or just a bad connection. You could also be getting that PO443 due to a bad O2 sensor, when the purge solenoid cycles,the computer expects the O2 sensor to react a certain way and when it doesn't the computer assumes the purge solenoid is bad. Hope this helps a little.

this purge solenoid should it be open or closed when taken off the car as in when i remove it from the canister should i be able to blow into the bit that goes into the canster and it come out the top cause thats what i can do at the moment thanks in advance

You should be able to blow air through it as far as I know. If you couldn't, that would mean your canister is blocked.

when i had it off i pluged it back in and got someone to start the car and turn it off a few times and could not tell that it was moving at all could this one part be causing my probs

Once after changing plugs and the car ran rough I noticed I had not tightened the air intake hose clamp. Could be you disturbed or didnt reconnect something after changing plugs.
Just a thought....

 

[puzzell]

was playing up before i did the plugs thats why i changed them thanks any other ideas

 

[puzzell]

took your advice and had a look around and found a spark plug with a big crack in it i am going to replace in the moring but still dont under stand why i was getting these codes and not a miss fire code on that cylender

Misfire Shudder, popping sound

Not sure why misfires codes dont come up, I had a real problem on the weekend. Scared the hell out of me. I was 480km upnorth when i got off of the highway. the truck had little power and it would shudder, sometimes a popping sound in the exaust when under load. I drove back home and had to hide behinf trucks since the headwind robed me of speed. anyways...

i checked everything no codes. good pressure in cylinders. Turns out the new plug wires i put on were arching out near a heat sheild. I didnt check because i assumed since they were new that it could not be the problem. Ive seen this with cracked sparkplugs. some mechanis sometime nick the end of the plug when they remove the socket and over time the plug fails quickly.


just my 2 cents and long story for you
