93 Plymouth sundance 2.2L, auto, throttle body injection, 180K. This model has no EGR, no MAF. Has weak power and hesitation, erratic idle, may stall at idle, may be hard to restart but always does. Does not matter if hot or cold. Some months ago fuel pump & filter failed and was replaced sometime before this problem started. Recently son has replaced plugs, wires, dist cap, coil, MAP, idle air control, O2 sensor. Have tested TPS, OK. Coolant sensor tests OK. NO codes and scan tool appears to indicate normal engine temp, advance, and other parameters. Can't find any connector problems or Vac leaks. I wonder if timing belt may have slipped to tooth or two on the cam? Is there an easier way to check this than cover, pulley, belt removal? Any ideas? Car is not worth cost of a dealer visit.
have the same problem?
