I just finished fixing my leaky fuel injectors, and as I was taking it out for a test drive, I noticed my TCS OFF and SLIP lights were on. I've looked at other threads and haven't really found answers or similar symptoms. Randomly, when I'm driving, my rpms seem to be limited to about 1000, and I really have to floor it to get moving. It also has rough idle when at stop lights. I've seen other threads saying that it could be an ABS sensor, alternator, or speed sensors I think. But my ABS light isn't on like other people have had, and I got my alternator tested a few months ago and it was good. I'm kind of lost so any advice is welcome.
Thanks!

You'll get TCS and Slip lamps from just about any serious engine code, because the ECM stops sending engine speed and that makes the ABS throw a C1130 and go limp. Check your engine codes.

Ah I see, I've had the 1320 code (ignition signal), but I didn't think it was related, thanks for the info!
