i have a 98 D1 and i was told the idle issue (revs up in park and neutral) was due to a fault with the ECU.
are ECU’s swappable ? my friend has a spare but i’ve read that they are not interchangeable but i’ve also read another ECU will “learn” the correct values for your truck with a couple of drive cycles. i could also get one from Will that is flashed but don’t know if that will work??
