ok so i bought this car, love it but went for a drive after 2000,miles of driving the car.... after 10 miles it coughs,, sputters..looses power and sounds like hell,, i have it towed to the dealership..$200.0 they tell me i need a water pump, clutch, and one cataylitic converter...total.. 15,000.0 i go get my car drive it home, and just because its christmas eve and i'm on empty i spoil my girl with a full tank of 93.... right.. the light comes on over my head,, ive ran 87 for 2000 miles i hit the highway it coughs again.. the dash light clears and wow.. running like a raped ape again... so.. question.... is this the fix? or the calm before the storm?
