when not in gear rev high but when I put in gear it dont have no rev no power and I can be flooring the gas pedal but car goes like 3 miles an hour
Let’s be clear. The RPMs do NOT go up when in gear?
If it is hard to get the revs up under load (in gear) and has a general lack of power, ask your shop to check for an exhaust obstruction (possibly a clogged cat) , or poor engine compression.
Is the check engine light on???
It may be in limp mode.
