Q: When giving gas car will misfire and shake badly
Some days when I go to leave in the morning crank the car and idles with no problem runs smooth. When I pull out, the is a very small incline and acceleration to speed up the car misses badly and will barely make the hill and continue to shake. No lights come on for a warning. I have driven on to the shop only to be able to reach 15mph max and had it towed 3 times. Each time when getting to the shop it runs perfect and will continue running good a day or two and do it again. They have changed fuel filter, fuel injectors (which it showed on the test once), catalytic converter, and a couple of sensors and can't locate the problem. Please help if you can. Thanks
