It will not idle right at all, the revs will climb and drop quickly from 250-2000 rpm. If put into drive it will occasionally stall. This problem started suddenly and I've taken it to 2 ford dealerships one (Crappy Sunset ford) wanted me to replace the engine saying it had lw compression on all cylinders. But I took it to another ford dealer and they said compression was fine at 125 125 117 125 with a small weakness in cylinder number 3. I've had the computer changed the o2 censors and vct sylinoid and cam along with the belt. Also recently the fuel pump was changed and its still runs rich and crappy. I've invested 2000+ dollars into it and it still doesn't run any help with this will be GREATLY appreciated. SVT Contour problem I recently replaced the IAC valve on it becouse it was having the high idle problem, this cured to problem for 2 days and now it is back again, did I do something wrong or miss a step? How quickly do these things die? Thank you.
