These are the errors stored in my PCM. No Check engine light is on. I used to run the 87 performance tune from torrie and all was good. Begining of summer i change over to the 87 econoomy tune to see if would save on gas. Mid summer the truck started having trouble at around 80-100KMPH. Like was stuttering and really hard time accelerating. Problem came and went. If i gave it alittle more gas it was fine. Checked to see if any soft codes. And p0300, p0316 and p1233 were stored. YEsterday i tried going back to the 87 Performance tune and OMG. If i gave it little gas, it was fine but as soon as i hit the gas pedal hard, the truck started sounding upset, didn't want to accelerated, sounded like it was backfiring. NOT good this was at any speed. I went back to 87 eco tune this morning and it seems to be ok when stepping on gas, but my guess is it will still do it at 80-100kmph like before. P1233 comes up as soon as i start the truck, but no light though.
