Hey all, was hoping someone could help me out with the issue I am having. About a month ago bought a 2004 Blazer and it had a weird noise in it. Under warranty, brought to dealer and after some misdiagnosis they found it to be the timing chain tensioner.

One of the issues they thought it was was the flexplate. So that was also replaced and while they were at it they replaced the tourque converter. The problem I am having now it it seems to be "flairing" somewhat 1-2, but definately 2-3. Also, while driving it seems that the RPM's are erratic. it will go from 2400 down to 2000 then come back up. like it is trying to shift arbitrarily.

Any thoughts or ideas?


Thank you
