Strange...

I just bought a '93 300CE. It has 170K but most everything has been replaced including the engine. It has slight rear end damage but hardly noticeable. I did not get a chance to drive the car but the seller and the previous owned were honest people. I was a little nervous but forged ahead.
I picked up the car in San Diego to drive home about 130 miles away. As I drove out of the lot onto a main street the gas pedal seemed unresponsive. I had to push it almost to the mat to get any power. Then I realized that I had to back off the pedal completely to get the transmission to change up. By this time I was on the freeway headed north. I also noticed that the cruise control was not working. I stopped for lunch about an hour later and when I got the car started again all of the above conditions had disappeared. It ran beutifully and responsively and the cruise control worked.
The next morning I started to drive it and the same thing happened again. By the time I driven 5 miles, everything was back to normal.
Do I have a throttle linkage problem? Any ideas guys?
(I love the car)

I would start checking by checking electrical components. OVP and voltage regulator. Make sure the battery voltage is good.

Your throttle cable may need adjusting.

Another thought - the 93 model year puts it close to where they started installing biodegradable wiring harnesses. Check the engine wiring harness for disintegrating insulation. More importantly, the electronic throttle actuator (ETA) may be made with this same type of wire. I assume your car has the ETA.

ASR? I don't know. I'll take a look and get back to you.

Arthur,
Oh damn!! Yes, it has ASR. The "triangle" is lit but not the ASR lamp on the lower lamp panel. I started it and the engine lit right off.
So do I have the dreaded "limp home mode" problem?

Arthur,
I just read your notes to the guy in Switzerland that had a 600. On my CE, it just got a new battery AND alternator so I don't think there is a low voltage problem. The car was hit in the right rear bumper area and I know there were some wiring problems with the stop light on that side.
I'll get it in to my mechanic tomorrow AM and look at any codes. Forgot about the 3rd light problem.
And if anyone is wondering if the car will drive at freeway speeds in the limp mode, mine did. I ran at 65 MPH in the right lane for 50 miles. Had no problems but did not stomp on the throttle. Arthur, thanks for your input. As soon as I find anything I will report back to the forum.

I don't think driving at 65 mph for 50 miles is the genuine limp home mode, but an imposter of some other variety, especially if you didn't have an ASR warning light. Not all limping is the limp home mode.

Unhappy

Just returned from the mechanic. He pulled the codes, then cleared them. He was getting ready to drive the car and see if any returned when he discovered there was no CE light. He pulled the dash and there is NO bulb socket or connector. We found a reference in the manual that some models (not California) do NOT have a CE light. This car origianally sold in Florida. Can anyone verify that some do NOT have CE's?
And of course, how do you know you have a problem, by the smoke billowing out under the hood?

Apparently this car has an Engine Control Module located back of the battery. The manual states: " Data exchange occurs between the engine control module (N3/4), the electronic accelerator module (N4/1) or Cruise Control/ISC module (N4/3) and the diagnostic module N59) in CALIFORNIA version vehicles."
My question is: What occurs on NON- California cars?

Do I need to go to the MB training school?
