'99 LS1 problem
I bought an '99 trans am 3 months ago and since the beginning it has had a weird problem.. The previous owner said it was caused by old gasoline, which clearly wasn't the case.
Every time I accelerate, at about 2200rpm, the car stops accelerating for a moment and then continues. This "lagging" happens on every gear and feels very sharp, it's like the car kicks back.
I've had spark plugs and their cords replaced.
Diagnostics say two oxygen sensors are faulty but I've had them replaced - twice. They also have a tendency to come loose by time which I think might be part of this problem.
Following codes usually appear:
P0137 & P0157
P1416
P0004
I live in Finland and unfortunately there aren't many shops here that can help me with my car.
