low rpms, engine shaking below 1000 rpm
94 accord lx A/T 168000k
At start ups, everything seems to be fine until it gets warm. My engine starts to shake when it goes below 1000 rpm and drops to 500 rpm at stand still. When i reverse out of my drive way...it feels like its gonna die. When I check the air coming out of the exhaust...it feels like its sputtering...like those old a$$ cars...it ain't smooth...is that normal? Things I've tried so far: clean egr, clean iacv, seafoam. replaced FITV. I changed my plugs, plug wires, cap, rotors a couple months ago when I still had this problem...didn't help. I'm changing them again tomorrow. I'm also gonna be doing my valve adjustment and my timing tomorrow hoping it will help. i think my cables are fine. Can anything else be causing this problem?

Sounds like you may have a vacume leak in the vicinity of the intake manifold causing one or more cylinders to run lean at idle, a dirty injector would show like this as well.

check your throttle cable, vacuum hoses, plugs, then clean out your egr, then check your injectors.
This is the order I would check from least expensive to most.
