Like the title says the recently purchased CLA250 4MATIC 2014 throwing this code but no others
Wife was on the way home from work .....stumbling and shaking she was able to get it about 1.5 miles to a acquaintances house until I could get up to see
Code reader only gives p0300 and the car does not store this code only when trying to idle smells fuely out the pipes
Did plugs and no coils at 100k about 6 months ago
Pulled the coils and went and got 4 Duralast coils from AZ as well as 4 new actual MB plugs from MB
Installed still same exact only maybe 5% better if that
Checked for obvious vaccum leaks with a can of carb cleaner very carefully when the engine was cold soaked this morning
No other codes that my simple Inova OBD2 will show .....did the alternator test and it showed good the car will idle better when forced to via foot pedal but still not drivable
If this were a timing chain issue do you guys suspect it would surely throw a code for that correct??
My next step is to see if possibly the EGR is clogged off or possibly the cat has plugged up but keep in mind this car was running perfect no chain noises no issues and this all hit while driving down the road ???
Tomorrow is a new day I may have to check a few more basics like fuel pressure and?? but it may also be time to admit defeat on my personal skill level with this complicated MB and have her towed to a euro shop
Thank for any quick tips I may be missing
