Hello. I have problem with starting my car every time. It starts fine, but the RPM start jumping and the weird part is when i give it little bit throttle(like 1500rpm) for 3-4 secounds It stops and runs just fine, like nothing ever happend. Ista did'nt find any codes, the long therm fuel is subtracting. Also it smokes hard when car starts. What i did before it happend was i removed the injectors. I havent tried anything yet. Maybe MAF sensor? Maybe injector vacuum hose leaks?

When im at home, i will make an video of it and post it here.

Cheers!

Today i found out that the exhaust manifold bolts are broken or its cracked, can it cause that?

Interesting that you could not find a code. Check out eccentric shaft sensor plug to see if there is any oil.

Finally, after more than 150km of driving, my car started to shake extra hard while driving and got those codes:


P0193 Fuel Rail Pressure Sensor "A" Circuit High
P2620 Throttle Position Output Circuit / Open
P0113 Intake Air Temperature Sensor 1 Circuit High (Bank 1)
P0101 Mass or Volume Air Flow "A" Circuit Range/Performance
P0237 Turbocharger/Supercharger Boost Sensor "A" Circuit Low
P1278 Manufacturer specific

Any sugesstions where i should start?
