Working on and off for years on this 1988 190E 2.3, trying to get it running well enough for a first car for a 16 year old girl - who is now 18!
Indy mechanic did all he could, replaced fuel pump regulator, and full electrical tuneup.
The car starts great and idles OK, and runs OK at light throttle, but as soon as the vacuum drops, it just falls flat. Put it in second and floor it, it just can't rev past 4000. I am guessing it is a fuel supply problem, filter is brand new and tank is full.
I do have a pressure gauge left over from my 1978 280SE. How can I check the pressures on this car?
What else can I look for? Clogged injectors? I keep hoping running some injector cleaner through will help.
Are there fuel filters other than the canister under the car?
I'll take any advice I can get, I am at wit's end and running out of time.
Thanks!
David
