Q: Misfire

asked by on August 19, 2017

I have a 5 misfire shakes when given gas, has new spark plugs, fuel pump, and engine checked

My car has 255653 miles.
My car has an automatic transmission.

You should have the computer checked to get the misfire codes to what cylinder is misfiring and check for spark from that coil and if you have spark at the coil then have compression on the engine to see if there is a compression problem. If it is okay and even over the engine then you would need to have the fuel injectors checked.
