RPM unstable...

[AllenRPS13]

my KA S13 recently had a problem, the RPM is really unstable... the car shakes like hell and sometimes it will die because of the RPM drop to under 300... any of u guys know what problem is that? any suggestion will be appreciate, thanks.

maf or clogged injection maybe? does it drag ass when driving? or just during idle?

I have the same problem in my SR, Every time I come to stop and push down on the clutch it will bogg down and try to kill itself. Sometimes the car actually dies out on me. I thought maybe MAF or IACV, but my SR is also running very rich, it backfires a lot, and I think maybe I am flooding the engine with fuel. Sorry to hijack but I kinda need to know what it could be as well. I havent had time to try anything out, but I dont wanna go pay for something expensive and it not help.

Thanks and sorry Allen for the threadjack

When my car was doing it, it was my IACV, I suggest cleaning it first and if that doesn't do it, then replace it, because it is expen$ive.
