Q: New parts, but scan says there are still problems

asked by on June 22, 2016

My car has been in the shop a lot. I have new spark plugs, new rear o2 sensor, and a new starter. When scanned it brings up the rear o2 sensor and spark plugs - but they are new! I can’t floor the gas - I have to baby the accelerator to get moving. My car just stutters along until it catches some speed. What do you think is causing all this?
