2003 Mazda MPV 4dr Minivan

200-horsepower 3.0L V6 5-speed automatic FWD

31000 mi C $100 Replaced Idle Air control valve at 50040. Stalling after hard acceleration when releasing the gas. Found the solution here: http://mazdaforum.com/m_49352/tm.htm 
58280   PCV hose failed. In 2004 Mazda issued a recall which our van had applied. Hose failed again. Replaced and it's all good not. Part number AJ51-13-89YB. 
85000 US $225 Broken PCV hose. Had originally been replaced under recall. Refused to replace again. 
65000 US $340 Engine was idling rough. It turns out the PCV hose had a hole in it (again). This was repaired a couple of years ago under recall but failed again. 
100000   Car was losing lots of coolant while driving. No puddles. Noticed coolant residue around water pump. Pressure test performed - no leaking hoses. Water pump was shot and they replaced it and all the coolant. Works great. 
67000 US $350 Coil #5 broke down. To replace it it required all the upper part of the engine to be removed in order to gain access. Therefore although the part itself was about 70$ the cost of labor caused the price to be 350$. 
68000   vacuum hose 
85000   Another ignition coil had to be replaced due to a misfire. DIY to avoid paying labor, $75 for the part. Also replaced air control module, $35 for the part. 
87000   Leak in the vacuum hose. 
53000 US $360 Ignition coil for one cylinder failed, causing rough running in wet weather and CEL to stay on. Required two trips to shop: two hours' diagnosis, which was unsuccessful, but shop swapped ignition wires around so that when problem reappeared, they were abl 
64000   Oil pan gasket leaked engine leaked oil. Necessary to remove part of exhaust to access oil pan, adding to cost of replacing gasket. 
78000   PCV tubing leaked, causing lean-burn fault code. Part not available due to holidays, but car was drivable in interim Parts received and installed to repair PCV tubing. 
80000   Rough running and stalling caused by faulty coolant temp sensor, causing CEL light to come on. Could not drive car except very short distance with cold engine. 
81000   Abrupt shifting, particulary 1 to 2 at low road speed, diagnosed as due to failed ring sensor in transmission. Sensor replaced. 
88000   For 3rd time, an ignition coil failed, causing short in wet weather; misfiring on 1 cylinder. Extensive labor to access rear cylinder bank. Replcd coil & rmng 3 originals. Also replcd plugs to avoid repeat of labor later (addl $ not included) 
90000   Coolant leaking. Replaced water pump. Rear heater not working; plugged line or valve possible, but will be evaluated at a later time. 
100000   Cooling system hose leaking; replaced 
107000   Piping to rear heater corroded and leaking coolant. Replaced with new parts - past extended warranty that Mazda has reportedly added for this problem.
