Wondering if anyone can help me. I have been having a problem when I start my car in the morning it acts like it has a miss or the spark plug is fouled. This causes the car to shake especially in 2nd or 3rd gear. The symptom goes away after the car warms up but every the miss is still there. When "miss" occurs I step on the gas the car sputters for a second and then it goes away. This is driving me crazy please help.
