Egr Valve?

[Uncle T]

I bought my girlfriend an 89 240, it had 2 leaking injectors so I replaced all 4 and now the car misses bad whenever you put it in drive and put it under a load.

New plugs, wires, rotor, rotor cap, fuel filter, etc... when I replaced the injectors.

My Uncle is a mechanic but doesn't really work on imports, I did the work in his shop so he came over and checked it out for me and said he thought it may be the egr valve giving the computer bad info when you put it into drive?

sound plausible?

any suggestions or ideas would be very appreciated
