I'm trying to start my van that has been sitting for 6 months. Usually I could just put in the battery and it would start. Is it safe to put starter fluid or a little gas in the carburetor to try to start because the engine is inside the vehicle once the doghouse is off.
My Chevy Van has a problem since a few weeks.
Whenever I demand a lot of power (going uphill on a freeway or driving a mountain pass) it begins to cough, looses a lot of power, car runs slower and slower and eventuelly the engines stalls/shuts off.
What can i do?
is it a problem with the spark plugs?
the problem only occurs when I need a lot of power
What seems to make the problem better or worse? worse in heat, cold and when the car needs a lot of power
How long have you had this problem? a few weeks
I need to fill my oil and it's not under the hood like my 1993. Some say it's inside but I don't know where. Please help if you can. And thank you!
need to know where the relays for the AC blower and the power windows
I recently had the automatic transmission rebuilt. The engine revs and the transmission does not shift out of 1st to 2nd until 20 MPH. The tech says this is about correct. I sense that the engine is reving too much in all the gears when shifting up. What are the approximate proper shift points from 1st to 2nd, 2nd to 3rd and 3rd to 4th in MPH?
Can't figure out where on the transmission it's located. It's actuall an '89 and the part is a bwd s8030, can anyone help???
