Hello,
I am an unfortunate owner of a 99 GTP. I've had a problem for a few years where the engine would start cutting out when boost was over ~25%, I looked into fixes at first but eventually accepted that it is an old car and I just need to be easy on it.
Today, everything changed. I was going around a corner when all of a sudden it seemed like the car was going to die. My idle varied between 500-1000rpm at first, then settled at about 1200. The boost gauge was at about 50% with my foot off of the gas. When I gave it even a little gas, the boost went to 100% and it did not go any faster. This is all happening between 5-10mph, that was all it would do.
Any ideas on what could be going on here? This is my only car and it is undriveable.
Thanks!
