New to the S chassis

Post by ThisGuyTR » Wed Dec 25, 2019 10:06 am

Hey guys.. not 100% where this question goes... lol, this is the Sht show i just got into.

so i just picked up a 1990 240 se with a swapped KA24de-T, i got the car about 4 weeks ago now non running, slowly been diagnosing all my problems. finally got it running and have just been working on all and little things. i like to try and do things the right way so, yes. ive been using the search and most of the problems ive fixed?.. i think lol.. so far ive done all the basics, replaced most of the sensors got it running okay. and now im stumped, will run but the throttle response is total trash... i found my 02 was melted to its self... replaced that and its a little better but im worried it fried the ECU, is there a way to check to see if my ECU is okay?

I'm not familiar with that ecu setup; However if you're still mafs you're going to want to recirculate that bov.
Also for your response problem check your mafs or clean it and TPS voltage. Im guessing your TPS might be bad.

On these older cars now as well try to look below the intake manifold and see if the knock sensor is cracked from the center out. I've found many doing this.

Welcome to the KA world!
