1 Answer

Sputtering I am looking to buy a 1996 astro LT,first i looked all over it and then took it for a test drive and it rode nice and smooth but when i took a right hand turn it started to sputter and when I got on top of a slight upgrade it ran fine. The owner said it was the three o2 sensors that needs to be replaced in order to stop this please help before i waste money on this van.

The O2 sensors can be pretty expensive, and it's his guess that those will fix it. It's not common for all 3 to need replacing at one time. I'd pass on this vehicle and find another.

1996 Chevy Astro V6 67K wont start when cold, needs engine starter fluid, ok when warmed up. Runs smooth. What is wrong?


I would say that the choke sensor (or whatever it is called) went bad & isn't telling the computer that it's cold & requires more fuel. Instead of starter fluid, did you try to push the foot feed 1 or 2 times?

Blazer uses lots of gas start up good then sputter when driven


Older 4.3 engines have a problem with the distributor gears. Put the engine on top dead center. pull the cap and mark where the rotor sets. Pull the distributor. Look at the gear. if it is worn/not a smooth touch, replace it.

Location sending unit


If it is a 4.3 L engine, it is located at the right hand side of the distributer as you are looking in at the engine. It looks somewhat like a mushroom W/ a wire going iinto it.

When driving the olds Intrigue and the engine will suddenly sputter and die. Dash lights come on and won't go off until I restart it. Restarting engine and it sputters like it is flooded, then it starts....


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. 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. 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

----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info
on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

'05 Astro van is "bucking" at low speed when turning left or righ


Sounds like you have a c/v joint beginning to go bad...Could be wrong.... but, I'm not there to test it! Look underneath and see if any c/v boots are torn... that will be your first clue!!
