Default Help my sc took a **** on me

I recently bought this 1995 sc300 about a month and half ago and little by little I've been replacing parts alternator , starter , battery , fuel filter ,so anyways yesterday night I put gas (93 octane) and as soon as I started the car it started misfiring a little bit . Then I drove for a minute or so with a steady throttle position and the rpm will drop for a second then pick up normally . I made it home with it misfiring abit. Now this morning it cranks and starts but immidiatly shuts off. Any suggestions? I pulled 3 codes 14 ignition signal , 25 lean a/f ratio,and 71 egr system malf. I've always had 71 but 14 and 25 are new

Sounds like one of your two ignition coils took a dump. Start the car, unplug one at a time, if the idle doesnt change when unplugged, you found your faulty coil. There is one on each side.

Thanks for the reply , a code I've been getting this week since Saturday was code 14 failed ignition signal ... The Toyota handbook says it's one of 3 things ecu , harness , igniter . On Friday my car wouldn't start at all finally with no present cel while the key was in on position so I knew my ecu went bad . I popped open the ecu and 3 of 6 capacitors were leaking . I sent it to get rebuilt I hope all my problems stop now ! Sorry for the long reply !

If the issues persist, I still think the coil(s) took a dump. My SC was running ok and it turned out the rebuilder said he was surprised the car was even running the capacitors were leaking so bad.
