Hey guys, i got a 80' corolla with a 1992 LS400 1uzfe n/a mounted to a W58.

I've taken the car for few rides this summer and even if it pulls hard and idle smoothly it show CEL #24 #25 #71 all in the same time.

I'ts smoking a bit black like if its running rich and i might have a real bad fuel comsuption ( hard to tell in this chassis at this point )

I got 2 front brand new ( jobber ) o2 and deleted the secondary, all 8 spark plugs are new, new plugs wires, both new rotor/cap, i've replaced my original 1/4 fuel line for 5/16'' one and mounted the oem ls400 fuel pump in my tank with a brand new in line fuel filter. I've already replaced injectors seals and the intake i'ts all torqued down to specs. The EGR is delete with custom plates and right stuff as a good gasket but i've leave the connector unplugs and rerouted lines.

According to my TOYCOM OBD1 reader i'm having o2 feedback

At this point i'm guessing a bad ecu or clogged injectors ?

I'm i on the right track ? Do you guys have any other ideas ? Thanks a lot !!

Cheers

At this point not a bad idea getting the ECU rebuilt.... I'm running rough as well and consuming more fuel than Robocop's SUX3000... My idle is shifty when its cold, so maybe something to do with cold start, or my ECU going out as well.....
