do you think that the occational hard starts(which also happen on flat ground, too), poor quality idle, and vibration apoun acceleration could be attributed to a bad coil pack or ckp and cmp sensors or something else. I also have noticed that the fuel economy is bad. By my rough calculation I am only getting about 14mph. From what I can see my motor and transmission mounts are fine and my U-joints are fine. I haven't found anything wrong mechcanically. I jacked the rear end off the ground (just to see what would happen)to see if I could recreate the vibration and I couldn't. I also noticed that on cold days when I start it up, it goes strait to 1000rpm ,it trys to go adove it, but it just can't. If I blip the throttle it will go to about 1500rpm like it normally does. any ideas? |
