my engine in my 1996 blazer doesn't start without a fight and my transmission wont allow me to leave a stop light in drive and i am wondering what the problems may be and how to fix them. if you can help please give as much info as possible. thank you for the help!

 

Can you post more information as in what it does exactly, and what's happening, or better yet a video?

 

the transmission wont allow the engine to go without alot of pressure on the gas when it is in drive. and the engine shakes roughly periodically when it idols.

 

Any codes stored in the OBD II??? most parts stores check it free, if you can limp it up there...
clogged catalytic converter, massive vacuum leak.
need more info!!!
