Hello

ok i am new to diesels and new to the forum

i need a some help

i bought my first diesel a few monts ago 04 lly wit 99000, now has 10500
it had a diablo tuner, i believe it has been removed.

everything seemed fine except feul eco was alittle lower than i hoped for.

itook a trip from tx to co with 25 ft campertrailer
on the way up there truck did fine. while i was up there (about a week) i drove around about 300 miles.i also let he truck idle 6 or 7 times for about 30 min at a time elevation was 8700 ft.

on way back i felt the truck jerk like a misfire, check engine light came on.
the truck has not run well since
found an auto zone scanned it and a p0087 feul rail pressure to low.

one more piece of info, before my trip my ac was acting up if i set it would blow cold, but if i adjusted it it would not engage compressor.i took it to my mechanic , he could not completely diagnose problem, but suspected my main computer may be bad. any relatin to my check eng light and bad performance?

any advice or info will be greatly appreciated

Joe
