Missing and jerking at low speed, worse with A/C

Symptoms

The engine misses or jerks at low speed and when pulling away, more with the A/C on

Likely cause

Owners traced it to a blocked fuel tank breather pipe, the charcoal canister, worn spark plugs or a weak fuel pump.

Fix

Check plugs and leads first, then the breather pipe and canister, then fuel pressure. Get a scan for stored codes.
