Hello, I joined this forum because I bought my son a 05 GP GTP Comp G last weekend and having trouble already. After getting the car home , cranked it up the next morning and it idled terribly. The check engine symbol started flashing and then stayed on. After a couple minutes the idle smoothed out and it ran fine. Took it to a friend of mine who owns a shop and he called this morning and said the car was losing coolant internally and said it wasn't looking good. I bought the car from Allen Toyota in Gulfport MS. (with no warranty) so I called the salesman who referred me to the mgr. (who got married yesterday) who wouldn't be back till Monday. So thinking worse case scenario , if I had to fix it myself, what was wrong and how could I fix it. I stumbled across your forum and looked up similar problems and found answers right away. Looks like they have some pretty smart people here so I decided to join. THANKS
