So I just replaced the spark plug wires on my 77 FJ40's 2F motor, in addition to the rotor and cap. I haven't replaced the plugs because I didn't have the right spark plug socket.
Following this, the motor is running rough. It doesn't want to start up regardless of the choke position. It does start, but it takes several long attempts, and needs to be in just the right choke position. Also, the engine sputters quite a bit when low in a gear, and it backfires.
This FJ40 is new to me as I just bought it. But there is a clear difference in how it's running now, and changing the wires and rotor is the only thing that's been done since it ran well yesterday.
One more thing- I smell pretty strong fumes. I don't know if it's fuel, or if it's the rusted out muffler throwing exhaust at me (top's off). The muffler needs replaced, it's rusted wide open. Would this actually cause the engine to run poorly? If so I don't understand the recent onset of problems overnight.
Thanks!
