- 99 VT Series 2 Berlina ecotek v6
Hi, have a 99 v6 Berlina. Having engine problems and no mechanic has a clue. Replaced the big end bearings and the lifters came loose so got them replaced after a little while. Before the lifters were done we were having power issues (no grunt) and shuddering at idle or low speeds. Was told it was the lifters so fixed them. Now appearently it is backfiring in the manifold. Got it plugged into a computer and it said there was a problem with the O2 sensor, got that replaced. Still happening. Any ideas. Mechanic has had the car for a month and I really need my transport back.
