engine light under hard acceleration

[Goldmember]

02 4x4 with 168K but new to me...Anyways under hard acceleration I get a check engine light that will go out after 15 mins or so. Tried to get it read with no joy...no history either. In a totally unrelated problem( or is it) my tranny seems to not shift when I think it should as in holding it in a gear when I think it should have shifted already to drop my RPM. Are they related I dont know but bothersome at the least...

my friend had a 02 7.3 that did the same thing he said it threw a over boost code cause of the mods he had done to it. boost peaked at 29psi. maybe the same thing.

chipped throws the light on. The edge instruction maunual talks about it and says basically to get use to it.

as for the 29 psi boost your right a 7.3 will trip the light I think anywhere from 21 to 24 psi depends on the vehicle they differed. He would need to get a boost fooler but the only cruddy thing is I think he will no longer know what boost he is pulling unless he adds a manual guage as well because the chip will read whatever the boost fooler is set at.

Check Engine light or Service Engine Soon light? I get a SES under hard acceleration. It is a soft code that resets itself, It does leave a code that an AutoEnginuity will read....it is just telling you that your HPOP can't deliver the fuel your engine needs now. Or at least that is what I was told.
