ok I have a 95 milly 2.5l V6 154*** miles my bro overheated a couple of times before we figured out the water pump was bad. so like any water pump job we had the mechanic change timing belt also no tensioners were changed. when my pops picked up the car he drove it for a while and the car started to shift funny and cut out like if it ran out of gas or something turn the key and it starts again after a while it does it again some times it took like 30 min to do it but lately it does it more often. i took the car to the mazda dealer for a diag. heres what they came up with P0725,P1170,P1195,P1250. they aid i need a O2 sensor the prc and rrc solenoid valves and teh boost sensor. now im a little lost because i have read some suggestions on what the problem is but i need more help. for example i might need a new Transaxle control module (tcm) or an ECU and i read that maybe my crankshaft sensor is bad or that the Timing belt tensioner i causing a slip on the belt therefore causing all the problems with everything else. this car seems like its never been worked on so i assume that everything is in place like vac hoses ect. does anyone have similar situation in the past. the car starts runs and after a while when u gas it bogges out stalls or sometimes it just launches after u think its goin to stall.
