Exhaust timing is camshaft not ignition. And for all 6 to be out would mean that the cam would seem to have slipped a notch.

SOURCE: 2002 audi a4 1.8 t cold start problem

It might be an injector problem.Sometimes if the injectors are not sealing properly they can leak fuel into the manifold even when the engine is off as there is still residual pressure there and you engine would be essentially' flooded' when you try start it again .After half an hour or so,and it would take some seconds after that to run normally untill the excess fuel is burned.

Have them checked and replaced if needed.

Please leave positive feedback if I have helped

Thanks

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

How to fix 2002 BMW M3 service code 11360212. The code says solenoid valve for camshaft adjusting unit Permanent failure. What part needs to be replaced or repaired?


the problem will be in the unit that is attached to the end of the cam shaft that is driven by the timing belt/chain. It is hydraulically controlled by a solenoid that gets the signal from the ECM. Replacement of the unit by an accredited specialist will be the fix.
The unit changes the valve timing by advancing or retarding the cam shaft in accordance to engine RPM

having PO 304 = Misfire cylinder 4,PO 306 = Misfire cylinder 6, as I read above you have done the most. The thing that you have missed is to check whether the Catalytic Converter is faulty or not. To get an idea check whether you have a smell like rotten eggs at the end of the exhaust,you start having problems with cat and needs replacement. My advice before you go for a cat replacement is good to visit an MOT center and check your emissions and then you decide,

Have 2005 lincoln aviator - has miss at 30-55 MPH - no codes replaced all coils ( ford) & spark plugs (twice) - repair vacuum leak at PCV Still misses -- no codes -- help


The COPS (coils) may have shorted the drivers in the PCM (computer). You should get a misfire code for each cylinder misfiring though.

Slim possibility, but very expensive unless you have a service contract.

ACTION: Diagnose engine for engine misfire concern. If diagnostics determine an engine misfire which is characterized by leakage through exhaust valve(s), only replace the affected cylinder head(s).
SERVICE PROCEDURE FOR VEHICLES WITH RUNS ROUGH/MISFIRE CONDITION:
  1. Perform relative compression check on all cylinders. If abnormal, check cylinder leakage and actual compression for "low" cylinders refer to Workshop Manual (WSM), Section 303-00.
  2. If leakage/compression check indicates a valve train concern, per valve train diagnostics in WSM, Section 303-00, replace cylinder head and cam assembly, pipe plugs and timing chain tensioner, per procedure outlined in WSM, Section 303-01.
  3. If cylinder leakage and compression tests are inconclusive, perform misfire diagnostic, per TSB 05-22-8. NOTE: DO NOT TRANSFER SPARK PLUGS. INSTALL NEW SPARK PLUGS IN REPLACEMENT CYLINDER HEAD AND CAM ASSEMBLY. NOTE: THE ENGINE MISFIRE CONCERN IS TYPICALLY EXHIBITED ON THE LEFT HAND CYLINDER HEAD AND RARELY ON THE RIGHT HAND CYLINDER HEAD. UNLESS CONFIRMED, THE RIGHT HAND CYLINDER HEAD SHOULD NOT BE REPLACED AS AN "EXTRA MEASURE" SERVICE PRECAUTION. NOTE: THE REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE ENGINE HORSEPOWER OR TORQUE ABOVE ADVERTISED LEVELS.
