I have an 02 Civic LX. Yesterday it started sputtering all the time and wanting to die at every stop. The check engine light came on and would flash about every minute or so. I took it an had the codes checked and it said that all four coil packs were bad, causing it to misfire. So, I had all four replaced and the problem is still there and it is still throwing the same codes but now saying that only coil packs 3 and 4 are bad. They are brand new.

It is at the garage now hooked up to a diagnostic machine. The mechanic is going to call me but he said he is baffled when I talked to him 15 minutes ago.

Any ideas? This is a college students car and she has to go back to class on Monday. Please help. Thank you.

I am NOT a mechanic and my car knowledge is virtually zero.

 

How many miles on the motor? Has the timing belt been replaced?
