'91 Full Sized Blazer dies when put into gear. - 10/19/2007 1:37:08 PM    themckeown   Posts: 1 Joined: 10/19/2007 Status: offline My '91 Blazer has been sitting for 1 year with minimal use and it has been gradually getting harder to start and drive.  I recentlly had a full major tune up on it  (cap, wires, plugs, fuel filter, etc.)  Now it will start but it will die when it is still in park or if I even put it into gear.  In order to drive it and keep it running (at stop lights or going down hills) I need to consantly put pressure on the gas pedal.  Also while driving it seems to have trouble shifting.  The power doesnt seem to be what it used to be and sometimes when i give it gas it will power down and I will hear a poping noise... almost like ballons poping.  The shop that I took it to said that the poping noise is a exhaust leak.  What should I do??

I don't have enough information to work with, (maybe somebody else does) but this sounds to me like a fuel delivery issue.. Specifically the fuel injectors and the fuel pump are areas of interest to me. The fuel pumps in Chevy trucks have never been the best in the world by a long shot. I'm assuming this is a TBI engine BTW. Also, when you say major tuneup, did that include the spark control module? What about the ignition module? Also, anybody play with the timing, see if thats where it should be? Exhaust leaks may make the engine run like crap (so would a blocked EGR valve FYI), but in my experience, all of the late 80s-early 90s Chevy truck engines have run sort of rough (by my standards) regardless of what shape they are in. < Message edited by BigGreenMonster -- 10/19/2007 8:53:55 PM > _____________________________ Don't tase me, bro!!!!!!!! 94 Blazer Tahoe w/ Vortec CPI- Flowmaster 40 series '97 30th Anniversary Mercury Cougar XR-7 4.6 Modular V8 (no major modifications) (in reply to thegr81) Post #: 3

If you have bad gas it won't run well. Thinking outside the box, I like it!!!!! Well, anyways, I think this is probably a combination of issues. Maybe a little transmission slipping too. Speaking of which, consider a transmission filter and torque converter flush. Most car owners never consider doing this until theres a problem. _____________________________ Don't tase me, bro!!!!!!!! 94 Blazer Tahoe w/ Vortec CPI- Flowmaster 40 series '97 30th Anniversary Mercury Cougar XR-7 4.6 Modular V8 (no major modifications) (in reply to Chevy Lover) Post #: 5

Not being a transmission guy, I'm only guessing _____________________________ Give a man a fish and he will eat for a day, teach a man to fish, and he will sit on a boat drinking beer for a life time (in reply to ShadowHawk) Post #: 7
