Computer is same gear ratios etc. This problem Im having now was before and after the computer swap. The stalling isnt always when brakes are applied, sometimes its just slowing down to make a turn, But usually it does happen when using brakes. And Im still new to these cars...Whats the IAC valve?

I agree with JR.////let'* split that hot fudge sundae! I had a similar prob on my 97....many of the vac lines were rotted...check all of the lines...and then check that the brake booster is holding vacuum....

Or simply connect a vacuum gauge if one is available. Here'* an example. It was put into a vac line, start up car to build up vacuum then turn off and watch to see if the system loses vacuum. Gauge really shouldn't move.

I have the exact same problem, I've replaced my plugs, coil packs, and air filter, I am replacing my cat this weekend I think that might be it on mine. Just in case we have the same cause I am or was running lean my plugs were super white. I don't have a vacuum tester but I am considering buying one in light of this.

Also I forgot to mention that mine ONLY dies after I let off the brakes not while braking I could hold the brakes all day. However it does chug a little while on the brakes, but it doesn't die or try to die till I let off. He mentioned too that it does this only around a half tank and lower mine also does this...I had my fuel pump, sending unit, and tank changed maybe a year ago so I really hope/think it'* not that. A few times by pumping the gas when it was dieing I was able to bring it out. I believe mine has gotten better after changing my coil packs it has started to not do it as easily, but I also had 1 or 2 bad ones.

Well I replaced plug wires and nothing changed, Today it hit a bad spell and was dying EVERY time I hit the brakes and slowed down (in town traffic) and if I gave it gas while breaking it would stay running but very badly.Once you come to a stop its fine, only while slowing down. Even after cutting it off for about 5 mins it continued to do it, Then, letting it run idle for 3 or 4 mins while I went in the store, and came out, and it didnt do it the rest of the day. Other then still running very stumbly at low throttle. If you hold the brake at a stop and try to idle it up a little it just jumps and bucks and runs horrible, the second you give it a little more gas it clears up and runs fine. Also do these cars have 02 senors after the cat? If not I may just gut mine to see if its a prob.

Yes they do have secondary O2 sensors and I am replacing mine because I think that may be part of the problem too, I think it'* leaning out the mixture. My cat and O2 went bad I'm pretty sure due to my leaking intake, it was like that for months.

The rear O2 is more or less a sniffer for Catalyst performance.. The Position 1 sensor in the rear manifold is the one used for fuel control
