i have a 94’ TLC. When i start the truck i have to wait about 10 minutes or i cannot drive the truck. If i dont wait and attempt to drive the revs drop very low and the truck stumbles/hesitates. Anyone have a similar issue? Anyone know a solution? Also if i drive the truck in traffic for a long time when i hit the gas it does a similar stumble and i have to pull over and wait for the truck to drive right again.
