Question: How do I fix this for my 1998 two door Blazer. The transmission is slipping when you get up to speed above 20 mi./hr and then it kicks out and back in and when I put it in reverse it spends to I turn off the engine restart it so I can put it in reverse taking out old fluid and putting in new transmission fluid in.
 You may have a shift solenoid going bad, or a sticking valve in the valve body. If the fluid change did not help, you are going to have to have a technician drive it to determine if the transmission needs to come out and disassembled and repaired.

Question: What could be wrong when i put my truck in drive it has rough idle runs rough?
 That could be a lot of things. A vacuum leak is most common. Also on the Blazer, restricted fuel injectors or stuck open EGR valve could be the problem, as well as bad spark plug or wire.

Question: My 99 four door 4w drive Chevy Blazer will not start now. Acts like it wants to but wont turn over. We have replaced fuel injector gave it a complete tune up and they bypassed the security and it ran for a couple days and the check engine light went out but now its doing the same thing and will not start again at all. I was wondering if there was a passcode that I need to reset it or a rest button? Please help...
 There is no reset button on any GM vehicle. You need to check fuel pressure. If it is a little low, the truck will not start. It needs to have at least 55 PSI.
