I have a 2005 PT GT dream cruiser edition 4, today i was cruisin along at a normal speed and all of a sudden it started bucking and sputtering (this being the misfiring im told) so i pull over and turn it off. it wouldnt start back up right away, just kinda sputtered. i waited a few minutes and cranked it again and it fired right up, however the check engine light was now on. anyway it seemed to be driving fine so i drove off, but every time i got up to about 2.3 or 2.5 RPM it would buck around and misfire again. i took it to radio shack and they gave me a code reading for a cam shaft sensor. well i cranked it and drove off and it was completely normal. no bucking even at 3 and 4 RPM. i drove home, (which was a 45 minute drive) i got 5 minutes from home and it started doing it again! i have looked for the previous posts on this and it seems they have been removed. can someone tell me if this has happened to you? and if so what do i need to make sure the dealer does to it, my warranty is up very soon. thanks!
