2008 Solara #2 cyl misfire

Did you replace the spark plug? What did the old one look like? Fouled?

Did you solder the wires when you replaced the lead? Did you accidentally mix up the wires?

No. I just twisted them together for the time being before I was going to solder them. There is power at the wires off the harness and power at the plug itself

I did replaced the spark plug. The old plug didn't look fouled

I would solder them and heat shrink the connections, maybe with two layers of heat shrink.

But there is power at the plug that plugs into the injector...

Yes but the connection is loose and may be intermittent.

Un-insulated wires will leak voltage and may screw up the spark timing.

Polarity probably matters so don't reverse the wires.

They aren't reversed. I hooked them up the same way as the old plug. I am getting spark at the plug as we grounded the plug on the block and started the car. I had the wires crimped but I can try putting solder on them instead. Thank you

Crimped connectors are not very good - sorry but it is true.

I'll try anything about now. My next step was replacing the ECM..that's the only thing left

You are probably not getting enough power to the coil resulting in a weak spark and a misfire. A proper solder connection should fix that. How about a few thumbs up?

It wasn't the coil wire that was cut, it was the injector wire

A weak injector pulse could cause a mis-fire. Thanks for correcting my typo.

Let us know how it works out and a Merry Christmas!

Ok thanks. I'll try it. Thanks for the advice

Merry Christmas to you too! Thanks

Hi. Still the same P0232P code...soldered and shrink wrapped the wires. Any different suggestions?
