AC Chuging & kicking

[ctaylor2]

My truck runs fine until I turn on the AC then it start chuging and kicking and then the check engine light comes on and gave me a PO339B code the first time and a PO3418B the second time and both codes will clear themselves after letting it set for about two hrs and starting it back up without the air on and then runs fine. Any one have any ideas what might cause this.

Thanks

Hi just asking again for help ?
I just had the air conditioner freion checked and found it alittle low so we put dye in it and recharged it and still doing the same thing. Engine still wants to chug and stall only after the AC has run for about 10 to 15 minutes. Again engine run fine without AC running.

Please Help Need Some Ideas

Finally found the problem with my 2000 s-10 chugging and near stalling yesterday it did it without the AC on and did it more frequently so took it to the dealer and guess what? Right it was the cam sensor!!
Changed it and no more problems.

Thank anyway you folks have always been a help in the past!!
