1985 190e 2.3 has been stored for 3 years

changed plugs, new gas, checked injectors, replaced fuel pump..

problem:

car starts up just fine but dies after 3 seconds... anyone know why this could be...

prior to storage i was having a problem with it idling low (700rpm when it was usually 1000) and when i gave it gas it would die, but if i stopped giving gas the rpms shoot up to 1200 then drop down to 700rpms

still new to working on this car so i :bowdown: to all who have mastered this vehicle... any suggestions/help will be greatly appreciated..

thanks
:)

adjust the mixture screw in the middle of the airbox. 700-850 is normal idle. whats been done to the car: fuel filter, seafoam, intake cleaning, plugwires, cap, rotor, etc.

changed plugs, new gas, checked injectors, replaced fuel pump (salvaged) and filter (new)

so far thats all thats been done.. not much experience at working on cars (something i am getting in to doing) the 190e was my first car.

it was idling at 10 when i first got it.. now it idles very rough... but i am assuming that you having me tighten the screw will help this.. will do pretty much anything you tell me to do to get this thing drive-able again.

thanks Jippi

the screw adjusts the air mixture. its the lean rich scenario, when making adjustments do it 1/8 turn at a time. i would suggest that you take the air meter assembly / fuel distro off and clean the throttle if it hasnt been done. also you have an 85 so the vac lines are about 23 years old, my old 85 had a similar issue and it turned out to be a vac leak. check for broken lines and rubber elbows.

Actually there is another filter that nobody thinks about it. Look at the gasoline distributor above the engine. At the entry there is a fitting that is equipped with a filter. Just take it out and blow some compressed air(big pressure) to remove all dirt.
Be careful it should be cleaned up fine. You have to blow(really) and have a clear air wave.

they screw we are talking about is the one in the center of the Air flow sensor plate?
theres a hole int eh middle of the air cleaner box. its an allen wrench type screw that is used to adjust the mixture.

looking at my fac manual and the diagram implies that the center of this shaft should depress downwards to activate an allen wrench device that turns an allen screw which according to the diagram is connected to the airflow sensor adjusting lever

problem i have now is i thinking it is capped or somethinng because i cant get it to budge
