service engine soon

[bourouba]

Hello,

I really do not know what happened to my car. i had the timing belts changed on the car, and when the mechanic started it the engine, it misfired codes. the mechanic said that this is the intake manifold. the engine rumbels more now and the wierd thing is that the odometer flipped from mileage to metric and they do not know what happened there.
did anyone run thru the same problem. knowing that the enegine was not rumbling as bad before i changed the timing belts.

any suggestions would be apprecaited thanks

timing is off or their is bad intake leak or the maf sensor.

take off the cover and check for anything pcv breather hoses broken. if nothing is take a can of carb clean and spray it at around the intake. if the idle improves then the area that you sprayed is the problem.

I bet when they took off the upper intake to replace the belts they cracked the intake by tightening the bolts incorrectly.

the lechanic changed the intake manifold, checked all vaccum lines. so now i had changed basically everything from timing belts including idler and tensioner just like when you take it to the dealer and now the intake manifold. but the car is still rattling and service engine soon light is still on. it comes up with 1471 and 1472 codes. and i really do not knwo why the odometer flipped from english to metric. i'm taking the car to the dealrship this wednesday to have the copmuter reflushed hope it will reset the odometer back to english. however , i'm still worried about the ratteling noise especially when i go past 50m and when it gets to 70 , it gets really bad.

the mechanic siad that he checked everything and still do not why why it is still doing that
