disconnecting MAF and no difference in idle ..

I always found the car heavy on acceleration
It’s much better now . I am able to activate them with the scanner .

Still sounding to me like it is an ignition-related issue, in terms of the miss.

Your mirror photo above is of the smog pump with rubber broken off on the nipple.

For the EGR valve, you may be able to just replace the gasket at the base, and see if that solves the problem. That is, if the EGR valve is not stuck internally.

Honestly, I would strongly consider just replacing all of the soft bits at the intake manifold and the top end of the engine. That would include all vacuum lines, gaskets, rubber nipples and connectors, black rubber air hoses atop the manifold, Tecalan tube that goes off the ETA, ETA gasket, EGR gasket, ETA rubber boot, rubber smog pump hoses, possibly the rubber donuts that mate the halves of the intake together.....the whole works. You won't regret it and it's a job that could be done in a day, or over a weekend.

This sounds like great advice. I'm just about to pull the trigger on a Beckman rebuilt ETA and would like to replace as many of these items as I can at the same time. Do you know if anyone has put together a parts list of all this stuff?

If you want ALLLLLLLLLLLLLL this stuff, then check out @gerryvz’s top end resto thread. If you want some cliffs notes, then here it is…. Cliffs notes info obtained over the years also with @gerryvz and @gsxr input

Just take plenty of photos when disassembling things.

You can also refer to my rebuild thread, as all of these operations are documented.
