As per my intro I have just purchased a 97 TJ which has a few issues.
I have changed all the brakes as they were in a proper mess and now I move onto niggly problem that I cannot get to the bottom of
I started with full tune up as a starting point
oil, plugs, leads, air filter, rotor arm & yesterday a new manifold
Its an odd one, when I start up all seems well, once up to temperature It has a slight hesitation/miss when at idle, it also seems to not have as much power, I also have slightly more engine noise noticeable from the passenger foot well area (US drivers side as I am RHD) almost like a sewing machine, not overly intrusive but I do not notice it at all when its cold
I have cleaned the throttle body & Idle valve, even disconnected the front O2 sensor which did not throw a check engine light or make any noticable difference....
now I am stuck, can anyone help??
