I hooked the duty cycle up again yesterday. Stayed at 81%, revved it up to 2500 rpm, got the engine over 80C and still 81%.
80% points to an issue with the IAT. Put ohmmeter on IAT, one way shows "OL" and the other way shows 0.00, so I'm guessing thats the bad part. Gonna order IAT and report back.

Been a while thought I'd update.
The harmonic balancer ended up exploding on the car (car sat for 2 or 3 years outside, I guess it rotted). Got it back together, still ran the same, got the replacement EHA from ebay, which was bad. Got a replacement EHA from the ebay seller, and put it on the car, ran the same, took it to the store, when the car went into closed loop, it died. Went home, took the original EHA and removed the set screw, and the insides were all F'ed up. Took the Ebay EHA that I had on the car that almost killed me the night before, removed the set screw and gave the adjustment 1/4 turn. Guess what? Car runs like a bat out of hell now. So to sum it up, my old EHA was totally f'ed. The ebay one I bought was good, just needed some adjustment. All is well now! Plenty of power and smooth throughout the power band. Thanks to ps2cho and tinypanzer. You guys were correct!

Hello guys,
Well, I was having the same problem as redassag00 had, that was about 1 month ago or so. i sent the car to the "mechanics" around "here". and all i got was a degraded performance. here are some facts: - No "Mechanic" here knows what the F he's doing. (they think that a turbo simply return the exhaust gas to the engine, and since the air is hotter its better for combustion. and a turbo is not irrelevant since I purchased a Twin-Turbo Mosselman KIT for my car and I should get it in a matter of days.) - Around "here" It is easier to get drugs and weapons or even get killed than getting a new part. enough whining.. the car "sometimes" runs perfectly, but Most of the times, i face the problem on 1/4 throttle the car stumbles and coughs then gradually accelerate. It consumes more gas than an F-16 fighter. i replaced: 1- Injectors. brand new original. 2- Spark Plugs. I know i know. the ones im using are platinum not copper, and i have no idea if they have a resistor or not. but still, they are brand new and was recommended by MB Dealer. (im not eliminating this possibility.) 3-Fuel Distributor. (complete) including the EHA and the Mass Air Sensor. 4-Coil. 5-Coil Plate. 6-Distriputer cover. 7-Transmission (irrelative but i thought its worth mentioning.) 8-Spark plug wires. 9-The Computer located near the passenger feet. 10-Feul Pump. 11-Feul pump relay. 12- O2 sensor is disconnected. and STILL the problem did not go away. One electrician said that the wiring harness of the main ecu (up in the passenger feet place) that has ends to almost every sensor on the engine, that needed replacing!! WTF! right?! any any any help would be highly appreciate it.

,one additional part to keep in mind is the fuel pump relay due to ageing / wear tear it can becomes very troublesome and leads to engine cutting out and engine reliability.
for best performance replace ageing fuel and voltage relays along-with all the fuses with new copper/brass tip ones .makes all the difference ! mak 103

eha
The car should run ok with the EHa disconnected-ok not in closed loop but so what...-think it was mistake to buy an EHA-simply disconnecting it should have been done and see if the problem persists. You eliminate and simplify your problem.
I just glanced through this post but thought you perhaps got lucky in throwing a part at it vs disconnecting the EHA entirely to start-maybe thats not correct as I new to this. Last edited by artony12; 01-05-2011 at 01:49 PM. Reason: misread |

Black plug on top is turned to loosen and remove. Pins 1 and 2 are jumpered to test fuel pump relay circuit. That circuit is hot so hit the holes straight. My expereince(have a 1991) is that when the FPR is gone - the car simply dies. What Osama describes - sounds more like the problem the original poster was having. Just my 2 cents.
