I'm a new owner of a 94 TLC, with 120,000, and have a two part question. I installed Toyota plugs/wires/cap/rotor a couple days ago and now the idle is down to 400 RPM. I simply raised the idle using the adjusting nuts on the cable. Why do you think the idle lowered from 800 to 400 RPM? The old plugs did need to be replaced (big gap and worn), but the remaining components looked good. My other question is a newbie one, does your 80 series idle up to about 1500 RPM at cold start-up and eventually idle back down after several minutes? My 88 FJ-62 never did this. Thanks!
