change intake gaskets you will find it blown thats why your problem happens when your engine is warm the alum. intake warms up and expands opening the blown gasket

Im having the same issue I believe. I have a 94\' Chevy 1500 and when i accelerate it will jerk like the gas has cut out but it wont stall. It just jerks and slows me down. It only seems to do it when going up a hill. I feel like it could be the fuel pump or possibly some intake gaskets?

i had same problem with my lumina it ended up having a blown head gasket. do a compression check and look for a low cylinder on the outside or twq cylinders next to each other that are low.if they are low it indicates a blown gasket. hope this helps

It's when the security light starts flashing that the infamous "chip" in the key becomes a nightmare to many.
Gradually the car begins not cranking anymore or if it cranks it would start and die in a second. Randomly it will
do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are
killing cars all over North America, they have a short lifespan and are certainly more effective against owners
than thieves. Here is how you save your car
1st trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like
that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this
in my regal for more than a year. If its shutting down while running, im sorry i have no quick fix... If anything
on this page helps you, please remember to comment or give me a thumbs up on the myfixya sight so i can have a
better rating to help more people on this. You can also Chat with me now as i have moved up in the myfixya world.
Thanks

Cheap fix: Bypass the chip in your key. Temporary, but effective. Until the TDM (theft deterrent module) in the
dash poops out, then you're kinda screwed. I was told that these types of key security systems have a 7-10 year
life span. Sucks for us. This link explains the "Key Issue" pretty well.

Never worry again fix: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it
out, and throw it away. I just did this in my Regal. Took about an hour. Took longer to find the thing than it did
to fix the problem. For a list of cars effected by this problem. See the NEWROCKIES link on the right side of
their page......... They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and
all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... Anywhere
from 600-1000 bucks. If you do buy this, please purchase it thru this link. The cost is the same, but i get credit
for the sale and im trying to earn my money back, as you will be able to do if you buy fron NewRockies and join the
