My car kind of jerks when I press on the gas. It moves but I cant really drive it over 45. It can be driven faster but I don't really feel comfortable doing so. Theres kind of a smell too when driven that fast. The "check engine" light flickers every so often. Normally when I'm going from a complete stop to moving. Theres also a clicking sound under the hood. The car turns over and starts fine. There's no overheating or smoking. Everything else seems fine.
