No Power at the Top of Gear My Trans Am is having some problems in the upper RPM range, from about 4k-6k.
Here is what it was doing. At WOT above 4k RPM the car would start to chug. It felt like intermittent losses of power. Kind of like I was pulsing the throttle, and this would happen all the way up to 6k.
However last night my friend and I were in the car and decided to get on it to see if could figure out what it was doing. Well I went WOT in first and when it got to about that 4k RPM mark it felt like it just stopped accelerating. The RPMs continued to climb but it felt like there wasn't any power left. The engine also sounded like it was really straining. I did this in first and second gear.
I am thinking this may be a fuel delivery problem but I thought I would post here to see what you guys thought. My car has the mods listed below and is un-tuned. Also it is at 61,xxx miles.
Thanks,
Alex
