I'm still getting to know the car because I've almost owned it. Under load in 4th, 5th or 6th gear the car starts twitching between 2000-3000rpm but only under full throttle. At high revs everything is fine. Replaced or cleaned: - Spark Plug DENSO TT IK22FTT, gap 0.65mm. - BERU igition coils x4. - Termostat Varnet. - Coolant sensor checked. - Throtle body cleaned. - Injector cleaned. - Fuel filter. - Fuel pump on igniton 5bar. After cleaning injector, car start fine when it's cold. But but when it heats up and stands for a while 10, 15, 20 min long crank before start. Turn off and start again all is ok, start now.. No fault code... Really out of ideas
Finally he turned on the check engine light. P0302 Misfire cyl 2 P0313 Misfire with low fuel I think the injectors are faulty..
Update: Looks like I was right about the injectors. Two injectors are leaking.. I ordered 4 new ones.
And finally, the injectors arrived. I installed them today. For the first few minutes, the car worked very poorly... I guess until it collected the new parameters. Now it runs great, no more shuddering and acceleration is smooth
