1995 lumina car 3.1 bucks in overdrive
I am puzzeled to what would make my car buck,or miss at high speeds ,pulling a gradual hill and when its warm ,wont do it when its cold,have put new plug wires in and plugs ,i just put this reman engine in and this problem exsisted with the old motor ,one mechanic told me it might be the tcc solenoid,also no codes or check engine light if i increase speed it will eventually go away.also in drive it seems to not be happening,other than this issue car runs good and idles like a kitten. anyone have any thoughts?
