The car listed above has a confirmed P0340 and a pending P0116, P0773 code. The customer told me where the engine was stalling while in motion and during that time the car just wouldn't start because the engine was very hot, but when they waited for an hour or more the car later started. What I noticed was that the car revved high intermittently on its own but will return to normal idle again about five second again, and the exhaust tailpipe was really darkened when I put my hand. Plugs, fuel pump and a relay (the don't know where the relay was removed though) was replaced by another engineer but the problem still persists. Please, how do I fix this problem?
Will replacement of part like camshaft position sensor fix this problem?
