p1300 p0300 at 4500rpm loaded
i have been searching the internet for about a month trying to figure out this issue. i get what feels like a fuel cut around 4500 rpm. if i hold it i get the p1300 p0300 code . i have a stage 2 for the hpt on my 99 . iv replaced Dic fuel pressure reg fuel filter iv replaced 2 charge pipes that were oil saturated from me blowing up the first motor due to sludge. drivability is fine around town and on highway but the min you try to punch it boom no power. im completly stumped. as to y this is happening. i do have a front mount no and when i got the tune i didnt have it . would that cause the computer to be mad . any help would be greatly appreciated. on one more note my battery is bad im about to replace it i do get proper voltage or what everyone says is proper voltage while driving with loads on im at about 12.8 to 13.3v with lights and blower on . but hard start in the morn . let me know

Honestly dude i had huge miss fire under load a brand new DIC ( PPS ) I do NOT mean a used one but a $206 from eeuroparts and new plugs solved the issue... check my video out it made this crazy sound under load. also do the bolt mod and try that it will help a little possibly but wont account for miss fires... have you ever changed the 02 sensor? do you have open sid? https://www.youtube.com/watch?v=wmRxQ_KEpDY Last edited by Saab95Aero; 11-26-2013 at 01:29 PM. |

That's teh correct plug and gap.
You coudl have a leak on vac or boost that only comes on under boost ( like a split hoe or loose connection in a line) What happens to your boost gauge? At a fuel cut you won't see the needle move all arond if it is it coudl be showing a leak I have seen this on a few cars, check all connections sometimes its easiest to hear or see on a dyno under load |
