Rough Idle/stalling 89 190e 2.6

[ichbdkevin]

Might as well try beating this one to death, but added input could sure help me here...

Just bought an 89 190e 2.6 and after a day or so, ABS light has come on intermittently...in addition to the Check Engine light.

Under high rpms while going uphill or over a bridge, or at stop lights, the Check Engine light comes on and car sputters and stalls out. The CE light has been coming on very frequently over the past few days (while driving and at a stop light) and the idle in "D" is very erratic - will range from 650-1100rpms, at times). Additionally, the starting is very erratic. Sometimes she starts right up (either hot or cold), and other times it will not start unless pedal is almost to the floor while cranking.

After looking through a hundred or so posts it seems like it could be just about anything from an OVP, to cap and rotor, to engine mounts, to a coolant temp sensor, fuel filter swap, or fuel pump relay.

I've cleaned the throttle plate and throttle body...that hasnt done the trick...additionally, former owner has recently replaced motor mounts...new plugs, and cap and rotor seem fine.

In your wise opinions, what would be the next logical step to proceed, short of going to stealership (which I will not, if at all possible)????

I'm running blind here without a shop manual (waiting impatiently for it)...so, next steps would ge GREATLY appreciated and would be willing to send a nice gallon of Jim Beam to the first tech person who can give me the correct answer to solve this f*&%#ing problem....I'm serious!!!!

Thanks.
