It's been at a mechanics shop for a week. He has run through every computer, electronic, mechanical test he can think of. He has even taken the engine physically apart, and cannot locate the problem. He says it sounds like the throttle position sensor. What do y'all think?
Thanks!
EDIT:
Compression now checks out at:
#1 - 186 psi
#2 - 184 psi
#3 - 185 psi
#4 - 186 psi
Is this too high?
EDIT (again):
Those compression values are when the engine is turned over 7 times. When the engine is turned over 12 times, they range from 189-194 psi, and when turned over 18 times, 195-199 psi. A thought just popped in my head, could a clogged cat be causing this entire problem???
Thanks!
