Hello all,
My 1999 LC (150k miles) has been temporarily slowed by the dreaded boiling-gas-at-elevation problem and I am slowly figuring out how to get it back up to speed. First step was fixing some bad wiring that eventually blew my instrument cluster (replacement TBD when I find an acceptable used one). There was a 12v current running through my fuel tank and also fried my sender. That has been replaced and the old cluster remains in the dash (and it doesn't smoke, crackle, and pop anymore).
The truck runs like it always did, but has issues when idling. It turns over fine and then idles so low that I can barely hear it (tach is part of the cluster that isn't working). Eventually, it stalls. It isn't throwing any CEL codes (OBDII is part of of the cluster that IS working) and runs just fine once it starts going.
Any ideas? First thought goes to the fuel pump since that seems to be where most of my issues stem from, but it IS getting gas so I'm not sure. Dirty throttle body? ECU needs to recalibrate? Buying and replacing the fuel pump isn't a huge deal, but if it's still good then why do it, right? Any input is much appreciated!
Semi-related: does anyone have much experience replacing the instrument cluster for the 98-02 models? Can I simply just pull off the light dimmer panel and top of the steering wheel cover to get it out? Or should the entire steering wheel come off? Thanks!
