1986 Toyota SR5 4x4 250k miles (almost) It was over heating... I installed a new radiator on monday. Yes, I put anti-freeze in it Today, it redlined on the temperature gauage after maybe 20 minutes of total driving time between leaving school, going to the bank, going home, driving to mcdonalds, and back... maybe a total of 8 miles. What the hell? Also, last week, it was doing this thing where it would jump.... like it wasnt getting enough gas or something. then it stopped doing that, and now it doesnt seem to be getting enough gas on start up. Bah.
