86 300E fuel injectors: Clean or Replace???

I have a 5-speed 86 300E. When warmed up it seems to have a bad miss when taking off in 1st gear, making a smooth getaway hard to do unless I rev it over 1800 RPM. It's not too bad when cold. It idles steady at 700 RPM but doesn't feel smooth. I've checked or replaced most of the ignition system so I've narrowed it down to a fuel problem, namely clogged or dirty injector(s). The car has 150,000 miles. It has plenty of power above 2500 RPM so I don't think a clogged fuel filter is the problem. At only about $20 each, should I replace them or get a injection cleaning?

Replace them!

I did replaced mine. For what I read, the new ones have a different and better spray patern. I think they are made of copper. Mine were original so they were due. The cleaning is going to cost you probably half as much and you still are going to take them out anyways. Make sure you also replace the injector seals, they are cheap.
Good luck!
