Prius plus engine problem

[Adam.hu]

Hello Everyone!

 

 I have a Prius Plus and I'have been struggling with the next problem.

 

 The engine jerks and the igniton jingles. 

 

No error code ind ECU system, but we made a live data monitoring test (enroute) and the computer signed 

ignition problem in changing piston. Once piston 1 and then piston 4 then piston 2 etc. but not continously neverthless the engine jerked all on the test way.

 

What we did for fixing the problem:

 

 - EGR valve  pipe and cooling system cleaned

 - Repleaced spark plug and coil

 - Repleaced air mass sensor

 - Engine cooling water level ok

 - oil consuption 0,5liter(0,13gal)-1liter(0,26gal) / 15.000km (9500mi) so its ok

 

Has enyone have idea? 

 

 Thanks Adam!

So the above oil consumption is in US gallons rather than Imperial. The equivalent in Imperial gallons is 1 litre/0.219 gallons.

I've heard of some Gen 3 Prius owners in the US (same powertrain in Prius+) ended up getting the ECU replaced due to issues with poor running.
