For anyone else looking into this, this sounds EXACTLY like the problem I am having, which I suspect is caused by a damaged bypass valve diaphragm. For mistubishi turbos, the part is extremely hard to track down, and all the volvos and saabs with this particular part at my junk yard had this already missing. It took me a year or so of progressively worsening symptoms with nobody being able to solve the problem to finally nail it. What you'll need (hopefully) is the TD04 Bypass Blowoff Valve Rebuild Kit from Mitsubishi. It's a $40 part.

P1027 measn the car is running to rich. you need a tune up could just be 1 thing. This things could cause it plugs, plug wires, cap, and rotor. The other code dosent realy affect the way the car runs its a waste gate valve control circuit. once you get some of the items i mentioned replaced your car will run great

Can you tell me if there ie an po035 trouble code for my 1996 oldsmobile aurora. a friend of pluged in his obd2 scaner and gave me this code. but when i went online to look up the code its not on any site

Hi, this code (P0035) applies to turbocharged engines. The stock engine for your car is a 4 liter DOHC. There is no turbo, correct? Recommend you have the car scanned at your local parts chain, then send us the code for repair advice.

I have a 1999 bmw 323i. engine light is on for fault code p0035, runs ok. but when EML light comes on car does run very rough. what is that mean? would you please give a hint of the problem? thanks

The error shows as a "Turbo Charger Bypass Valve Control Circuit High" error. Let me guess, you don't have turbo, right?


Did you recently "top off" your last gas fill? If so the error might go away on its own.

Is there a lot of moisture where you live? Ignition contact might have gotten wet.

Possibly a piece of carbon blew out of the manifold.

Does the car stall when you stop or while taking turns slowly? Might be cam position sensors.

Sorry for the vagueness but without using a Peake analyzer tool to isolate the problem it makes it difficult to give you the exact reason.
