Stumbing/hesitation on M104 engine
Our 1988 300TE with a 1995 C36 engine (AMG'd M104) is experiencing a stumbling/hesitation on acceleration between 2800-3200 RPM. It also doesn't feel as powerful at the higher-RPMS.
This is a hybrid car. Think of it as a 1995 E320 W124 wagon with a C36 engine, computer, and tranny.
The car had all filters (air, gas, PS, self-levelling) & fluids (oil, ATF, diff, PS, self-levelling, brake) changed about 3K miles ago. Plugs & plug wires were changed 10K miles ago.
The car starts right up, no problem, and it feels like the entire engine is stubling/hesistating to accelerate.
No "CHECK ENGINE" light is on.
What's the proper diagnostic procedure?
Do I need to get the Mercedes HHT connected to read-off some codes?
It happenned 2-days & 80-miles after my last fill-up (ARCO Premium). Should I change out the fuel-filter?
The car has been in the rain for the last 5-days (we're remodeling). Should I check some connectors and clean them up?
Thanks in advance and Happy New Year!
