Question about 1997 Chevrolet Astro

1 Answer

I have a 2000 astro van awd. 1/2 the time there is a hesitation upon acceleration and sluggish, like it is being held back. I had it checked out at a chev dealer and everything is ok. sometimes it takes a few seconds for it to take hold and go.

    Hesitation when engine is cold. Gets better when engine warms up. Feels like hesitation is at about 2000 RPMs. When accelarating, and cold it just boggs down. But when RPM go above 3,000 it pulls hard.

2000 chevy astro van 4.3 v6/I changed dist.cap 4 times in 1 year rotor too/runs rough,hesitation,bad ildeing,could it be dist.gear /shaft are worn/got code po300


code p 0300 is random/ multiple misfires
each p 0300 code ( 0301,2,3,4 etc) indicates the piston at fault
this code can be from electrical , ( cap plugs wires etc ) but is mostly attributed to problem injectors and ecm injector controls --wiring and connections
check the other areas for the fault as you may be concentration on the wrong area

Will this transmission bolt up to my van I have a 2005 astro transmission is bad. Found one with OTAD on the identification sticker. will this tansmision work?


otad doesn't help ---did the trans come out of an 05 astro van s-10 blazer /jimmy s-15 or safari and it your awd because you need to match the rwd with an rwd and a awd with an awd /4wd from above and the unit has to be compatible with the 05

98 Chevy Astro van AWD bucks & extreme hesitation on initial acceleration. There are no codes in the computer & check engine light is not on. We replaced the spark plugs, wires, distributor cap and...


I'd check for vacuum leaks next. use a spray can of intake or brake cleaner. spray around vacuum lines, manifold gaskets etc. if the rpm increases you found a leak.

Engine would not accelerate, now wont start


Sounds like the fuel pump went. Check for power under the van at the gas tank for the fuel pump. You need 2 people to do this,the pump will only power up for 5 secs/key cycle unless the engine is running.

Sticky throttle on 200 Chevy Astro


There was a recall on the throttle body blade on the 4.3 a few years back for the throttle body to stick in the close position. Yours being 9 years old makes me think that there not going to do anything for it but give you the solution to the sticky throttle blade.
The solution was to change the blade. You can try cleaning the throttle body blade by spraying throttle body cleaner in to the barrel of the throttle body. If you look down, you'll see the carbon build up and it may just need and good cleaning. 
If that does not work, you can buy a new Throttle body blade which is only held on by two screws on the throttle blade shaft.

Start with cleaning the blade and throttle body with throttle body cleaner. Just follow the instruction and you'll be fine. 
Keep me posted and good luck.
