pa-pa-platypus Posted May 31, 2013 Report Share Posted May 31, 2013 The first problem I have encountered is there seems to be a miss upon take off... gets really sluggish then kicks in and runs fine... it also idles rough.. almost like it wants to die Nex issue is it seems to run on the warm side.. has gotten real warm once but went back to "normal" Which is about 235ish degrees from what I can see Suggestions would be appreciated This isn't teeball.

tacomaguy1 Posted May 31, 2013 Report Share Posted May 31, 2013 idles rough in park or with the brakes on in drive?.....They have a common problem of the brake booster leaking. When the brakes are pushed it will introduce a vacuum leak and idle rough, when they're released it's fine any vacuum leak really idk something to check, it happened to my blazer.
