Need help troubleshooting intrepid problems!
I have a 2002 dodge intrepid es v6 3.5 95k miles. I bought this car from the original owner with minimal wear and immaculate interior. Ive only owned it for about a year and up to this point have already had to replace an exhaust, resonater, wheels and tires, brake lines, brake pads, rotors, tie rod ends, and probaly a few more things i left out,About a month and a half ago i put my car in the shop to have the exhaust parts welded because the guy who installed them did not have a welder to finish the job. After i got the car back and drove it on the highway a red light on my dash came on and it overheated for the first time ever. I had it towed to a garage and first replaced the thermostat. It didnt solve the problem and the mechanic found a tiny pinhole in some 3 way pipe he said connected the thermostat to the radiator overflow. So i replaced tht 148$ part and it still was overheating. Next i brought the car to a different mechanic and replaced the water pump and timing belt 130$ parts and 240$ labor. He told me the head gaskets were blown and needed to be replaced. I bought the head gasket set for 200$ through autozone and had it replaced for 350$ plus 150$ for resurfacing of each head (75$ each)
Now it doesnt overheat but i am faced with another problem. My check engine light was on before all off this for p0700 and p0740
Now i have many codes appearing after i clear them and drive for about 20 miles the light comes back on .
Codes are as follows:
700 trans control sys malfunction
171 system too lean
740 tcc circuit malfunction
562 system voltage low
300 random/multiple cylinder misfire detected
I am aware i may have a vaccum leak which could explain the lean fuel syste. Yesterday i checked the tranny fluid and it was a little low so i added some. I know the transmission pan has never been dropped and the filter has never been changed. Should i bring it to the dealer and have them do this ? I am not very mechanically inclined and considering selling this car before dumping more money into it. Any help will be greatly appreciated ! Thanks
