My 1998 Toyota Camry 2.2 eng. 4 cyl. Is still stalling when cold, and has also started this new, when I put on brakes It either stumbles or stalls out completely. I have replaced EGR Valve,Vacuum Modulator, VSV,Engine Coolant Temp Sensor, cleaned trottle body. Any additional info would be greatly appreciated.

The coil may be breaking down under load. Also, the idle rpm may be too low. I would also check the Idle Air Control Valve (IACV).

Try this, pull the vacuum hose to the brake booster. Seal the hose and try again. See if anything changes.

I have cleaned the throttle body and IAC valve, also checked resistance on the first O2 sensor and on the IAC valve it all checked good. It also stalls when you hit the brakes real hard. Also when you take your foot of the gas and you are slowing down it slows down to about a 1000 RPM then accelerates to about 1600 then it will slow down.
Any info you can give is appreciated.
