So I recently adjusted my valves because all cylinders were misfiring still couldn't get it to start. So I cut the catylic convertor off and she's starting, took a drive for 5 miles and it was slow to accelerate, didn't seem to want to shift and right before I got home hit a stop light and when it turned green went to press the gas pedal and it didn't want to go but two miles an hour. But everytime I released it gave it a lil boost. So got it home and went to take a test drive the next day nothing when I press on the gas. But when I just had it in drive not pressing the pedal it will go slowly. Any suggestions?
