So after reading the codes, the following were issues: 1. misfire due to low fuel 2. P0171 too lean- bank 1, and 3. P0174 too lean- bank 2.
I decided to inspect the vacuum hoses, and found a decent sized hole in the upper intake boot. The popping was from the coil popping against the valve cover on cylinder 3. The head of the spark plug was stuck in the coil while the plug itself remained in the cylinder. Upon changing out the Bosch plugs with new Bosch plugs, the following codes were read:
1. P1343 misfire cylinder 1 with fuel cut-off
2. P1344 misfire during start cylinder 2
3. P1346 misfire during start cylinder 3
4. P1350 misfire during start cylinder 5
5. P1352 misfire during start cylinder 6
6. P0171 system too lean- bank 1 due to large vacuum leak
7. P0174 system too lean- bank 2 due to large vacuum leak
I cannot replace my ripped upper intake boot until my dealership opens Monday. My question is, are the misfires during start due to the Bosch plugs? Has anyone had any problems like this?
