i was told that this could be a boost leak or a vacume leak it feels more like a lost cylinder to me! i just bought a one owner 2002 rex 150k miles, one owner, clean title, no problems or obvious leaks under the car. i can hear the tubo just fine but it coughs and sputters some times and the check engine light comes on. i can push in the clutch let it idle down and it's fine and the check engine light goes out. please help me with this!
thanks for all the help. while i was changing the plugs t found the problem......broken retainer clip on a CP harness! all that worry over a 1 cent zip tie fix the plugs were all fairly good. the timing belt has been changed @ 95k i only run 93 octaine i hope i have no more problems to contend with!
