98 svt 50,000 miles

Purchased the car around 36,000
Every now and again it will stall when coming to a stop.
Idles fine most of the time right at 750.
Sometimes it will drop around 500 and I blip the throttle.

Changed the intake recently to the pipe from BAT Inc.
with a new air filter.

Seems to be running cooler than normal now!
Used to run in the upper R and now it is in the N-O range??

Could this be the intake install?
The temp outside is around 90 F

Today the CEL came on with a 0133 code O2 sensor slow...
P0133 O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)

I cleared it, will see if it comes back.

I've changed plugs, wires, waterpump, brakes, tires/rims, oil every 3000, etc...

What else should I look into?

Thanks!

Are you sure you have all the sensors and hoses plugged into the BAT pipe properly?

I had to seal my IAT sensor in there with silicon. I also had issues with the pipe that comes from near the IAC on the right rear of the UIM to the BAT pipe. If this tube is not on tight...the car will stall instantly. When the car heats up so do all the materials in the engine bay...maybe try using a clamp on this tube.

Also check your engine air filter. This is just to the left of the IAC on the rear of the UIM. If this gets dirty...the engine will stall as well.

When I installed the pipe I didn't use clamps.
It stalled right away and I clamped them all.

The stall problem was prior to that though.
Not sure it has stalled since, I know it has dipped under 750.
I'll have to check that filter.


They changed the design a little by adding a grommet to help seal that sensor in the pipe.

No leaks that I know of.
I'm thinking about cleaning the TB/MAF and possibly replacing the IAC.
