Hi,
I recently had a problem with my '97 bird (3.8L). It seemed to misfire at idle. About 2 years ago I put in Bosch platinum +4 in. I've heard other people having problems with them and assumed this was the case. Then a couple of days ago it was misfiring so bad I had to take action. I said F-it and bought a OBD2 reader from autozone. It read P0300-multi misfires. I tested the first coil and had secondary resistance. But the second one didn't. Though the second coil had primary resistance. I replaced the second coil and everything is running good. After all that my question is 'starting on the first crank.' Whenever I start my car almost always it won't start on the first crank. But it will always fire on the second crank. I always thought it was the +4 plugs. Now I have plain Bosch platniums and new Bosch wires. Anyone have any direction were to start? I'm getting no codes now. I changed out just one of the coils. Should I change out the other 2? They both showed secondary resistance. Any ideas?
