2018, Toyota Camry SE 2.5 l.

It has brand new spark plugs. It has brand new fuel injectors. I changed the coils and the same codes pop up. I checked the spark for the coil on the spark plug and it is good. The compression is good. I cleaned the mass airflow sensor I cleaned the throttle position sensor.
Brand new fuel pump and fuel filter.
I cleaned the 02 Sensor.
I am not sure what else it could be.
When the car.
Is first turned on. It only has a little bit of a misfire. When I disconnect cylinder two, it will miss fire more. When I go to drive it, and I push on the pedal It will start to lose power. And miss fire 100%
Then, after that, when I disconnect cylinder two, it doesn't make any changes as if cylinder 2 is dead.
Everytime i turn off the car and turn it back on. The car is good again till i accelerate again on drive and misfires again
Thanks , my car shuts off when driven and the engin warms up, at first i taught all kinds of things from throttle body to others fault , but the mechanic said its the computer box that faulty but the engine starts normal but cuts off on long drive
Same with My 2014 Cadillac ats
Obd2 works fine keeps throwing the same codes for crank sensor and can sensor. After replacing them both.
Have you checked the wiring?
Thank you. My 2005 Corsa C will fire up but won't run go
for more than a few seconds. New pump, filter, 50 psi, new oil switch, new crank and cam modules, new plugss, removed throttle body and cleaned, maf cleaned...
But no fault codes either with pedal test or three obdii readers inc Xtool D7. I 'm suspecting a bad ecu. Your opinion pl ease!
Which engine do you have in it?
@@MechanicBase Wow, thanks for replying. Ecotec. I'm pretty sure it's the Z14XEP. Opel Tigra Twintop X04. 1.4, 90CH 66kw.
I was thinking of forcing the ecu to record some codes, e.g. by partially removing the air intake tubing. Can't find anything on such a strategy. What do you think? Thanks again.
if the vehicle reads overheating I have a several questions. Do you have a instagram I can reach you faster
Can it cause limp mode to set. Instantly after resetting the the computer.
Do you have any codes?
3.8 L in 2006 Buick Allure 210,000 KMS car shut off while driving cranked no start had code P0650 No Check Engine came On? mechanic replaced fuel pump 3x coils & crankshaft P.
