Their is on 101,000 on the car. The cat is still on their, but they did say I would have to replace it within the next year. The cat isn't running hot or anything.

lol the cat is supposed to get hot

Haha well I mean like overly hot, like about to explode hot

RX7's run rich. But with good working cats, you shouldnt smell it. Without cats, even a well tuned one will smell like gas, just a rotary thing.



I doubt the mechanic could tell it was running hot from driving behind you. You would probably know if your engine was running hot, or of the temp wasnt normal.



As for the stalling, double check that all your sensors are connected, and vacuum lines are in their proper places. Its probably something that got taken off when the headers were being done, or got knocked loose when the headers were being done, and not put back.

I've never seen a legless, midget mechanic before! https://www.nopistons.com/forums/pub...#>/biggrin.gif

Their was a vaccuum line that was unplugged, but I am not sure if that one little line would cause all of the problems I was having.

you haven't been to indiana before eh? lmao

you'd be surprised. one popped off of my FD and the engine surged like crazy at idle till i found the leak

It doesnt really feel like surging...the only thing that I am feeling when I drove the car was that everytime I came to a stop it would stall (it is an automatic) if my foot wasn't on the pedal giving it gas and revving it, and it didnt seem to want to shift...I don't know how to really explain it. When I had half the header done (it was clamped to the cat and the O2 sensor was just placed on the bung) I pulled it out of the garaged and just slammed the gas, it drove fine then, had a lot of power and such...maybe that blew the line off...but I dont see what would cause all the driving and stalling problems.
