I have searched these and didn't really get an exact answer for exactly what they are... 14, caps or ecu related? 42, speed sensor? Couldn't find 24...
Reason I am asking is because I am having the same problems a lot of people have with their 1jz, the break up around 3500 rpm's, tach goes crazy. . I have already checked the plugs, replaced the coils because of cracks. Checking engine codes before anything else, but I've read other people's problems like the fuel dampener, fuel cut/or bad filter, bad plugs, wiring, tps, bad coil connectors (which mine stay on, but not all of them snap on, brittle and they were broken, most likely my next choice) etc.. Engine was rebuilt, and wiring harness extended, everything pretty much stock besides intercooler, pipes and filter. As far as I know the fuel pump and filter are original, have not looked but the car was pretty much stock before me as well. I'm needing to find out the codes so I can continue to try fixing my problem, any opinions, suggestions and tips are greatly appreciated. I try not to post up too many problems being they may have been gone over before... thanks in advance!
