low revs
my 97 ls400 revs low when i approach a light or have to slow down, the revs go so low almost to the zero then before it stalls it shoots up again, i just wanna knw whats going on, and why it does that, the check engine light was on so i put the computer on it and the code was for the egr valve, i got a new one and it still does the same thing, i was thinking its the spark plugs but I'm not sure

so today i cleaned the throttle body and it was filthy!!!! it was so bad i cleaned out the whole intake manifold and it was filthy, so i put every thing back on and it still does the same thing, now the next thing I'm going to do is the spark plugs, wires , cap and rotor, hopefully that fixes it, but if its not that then who knows what it cud be
did you clear the EGR code? low revs is typical and usually a TB cleaning brings it back up. there is also an idle control valve that gets gunked up.

lets say it comes back, what is another way i can solve the egr problem? my check engine light came one like 2 3 weeks ago so i checked the codes, it came up with 2, 1 was the egr, 2 was my catalytic converter, i checked the egr, it looked bad, so i ordered the part, by the time i got it in the mail, the check engine light had came off by it self, i took it to get it smogged and the code still came up even tho the check engine light was off, they did not erase the code, and i just put the new egr the day after
