I have a 2007 mitsubishi eclipse 2.4l and I recently had to change the crank sensor. Before crank sensor went bad car ran great and was daily driver after I changed crank sensor it runs and drives great as long as it is on flat ground but has no power to go up hill. How do I fix this

Hi, i think i answered you in another post.
If not then the likely cause of your problem is turbo related the most common cause is one of the pipes going to the turbo has a small split in it causing this problem.

Nearly all the diesel turbo cars with your problem usually means a pipe needs replacing for the turbo this will need to be checked as it can be difficult to find the damaged pipe because they work under high pressure so actually seeing the damaged part can be difficult so check properly.
If you are unsure then get a garage to check this as they will know the fault and will have a good idea exactly which pipe is damaged.
Worst case of this will be that the turbo needs replacing but this is in the most severe of cases the turbo can blow if the pipe has been damaged for to long as it will be working under the wrong pressure.
What happens is when you acelerate the turbo builds up pressure giving you more power when you need it but when the pipe becomes damaged this pressure is lossed and you then lose power and will cause black smoke coming out of exhaust.

Hope this is some help to you but if you have any problems or questions then give me a shout back and ill be glad to assist you further ok

Great reason to replace the converter! I would be wondering about the Oxygen Sensors but you have already thought of that. I'll get back to this when my brain wakes up.

not all hdi injectors are the same and there are some tricks to replacing the injectors so be careful as you can cause saver damage to your engine if not done correctly.
as the other gye said it may be a turbo pipe but Peugeots being Peugeot it could be any thing your best bet is take it into a dealer and get them to put it on the PPS to diagnos it properly

Is this a V6 or 4cyl???>>>(V6) This requires removing the Harmonic balancer (crankshaft pulley). Remove (R) front wheel, remove engine splash Guard, Remove crank pulley, remove lower timing belt cover. The Crank sensor is located behind the crank shaft pulley!! I highly recommend having this done by a certified tech, requires special tools. Hopefully this helps!!
