Later EZLs have a DTC readout but not in 88. You are aware that in 89 Mb changed the camshaft profile for a smother idling engine. There very well may be nothing wrong with your car as the early cams are known to idle a little rougher than the new profile cams.

Personaly I think the early cam has the potential to make better power than the later cam. If I remember correctly the early cam has a smidge more duration that they took away from the later cams. I'm going to do the head in my 90TE soon and I'm going to pull the cam and rockers out of my 92TE parts car b/c it has an 89engine in it. I've done a lot of work to my 90 but it still just doesn't pull down low like the one with the 89 engine in it did.... not even close, really. I've chased and fixed a lot of demons in the 90TE but I think that the weak low end is the later style cam. I've got several mods happening when I do the head on my 90 so a stronger engine won't prove my point but if it is still weak down low then it will at least disprove it and I can keep looking for my low end power.
