How else can I check my MIL codes if the previous owner did not wire up the MIL light?

I know it sounds stupid but is there any other way to scan the car via diagnostics port?

Or does anyone have any idea where im supposed to run these wires to for connection?


Aristo motor, 94 SC300 combo


Car is still misfiring and I would really like to know what the ecu is saying to point me in the right direction.


thanks

non obd2 will not tell you which cylinder is misfiring. hook it up to a scope to check for misfiring.

I will do that, Im just wondering if its something like a cam angle sensor, or a TPS sensor, or something of the sort.

I already swapped, coilpacks, map, and ignitor and its still there.


I can kinda partial throttle the car to about 9psi and it pulls perfect but if i go 100% throttle it will break up at anything after about 10psi or so by my in car gauge. car has brand new NGK 6s gapped at .028

the ngk website says that if you are having misfires at high rpms or boost to lower your boost or open the gap on your plugs till it quits. In my personal experience though id say to check the fuel line for blockages or clogged filters because i used to have an '86 mitsubishi starion that was a 2.8 turbo and when it went above 7-8 psi. the thing sounded like it was gonna blowup. it would pop and bang and misfire like there was no tommorow. so i thought it was th fuel pump going bad and i went to replace it and i pulled the fuel line off and it looked like it had something stuck in it. i pulled it out and it was a cone shaped filter clogged with a light brown paste. well i put it back together and took it for a testdrive and i could hit 14 psi. and 6500 rpms with not one misfire. i never had another problem with that again.
