codes 24 33 and 34 now present have it running it idles at 1000 then shoots to 2500 and idles out at 1500 when given gas it will it rise pedal input then dies shortly after releasing pedal

 

You didn't hear this from me, but instead of spending money on a new pipe, and making what you did obvious, just drop the cat and "clean it out" with a long screwdriver or some such implement, then put it back in place.

 

It also appears that you may have a serious vacuum leak, possibly around the #1 port where the gasket is not well supported. The factory gasket gets sucked in at the top outboard corner, just under the power steering pump. Replace with a Felpro, they have a metal backing in them that helps them to resist being drawn in by the vacuum.

 

im not doubting you but it never had a leak like that before.....could it be it just all happened at once?

 

The SL/SL1 engines are famous for this. I have had two factory gaskets fail, I now have a Felpro intake manifold gasket and it has worked for the last 120k + miles. If you look at this area, you will see that there is no stud and nut on this corner of the manifold because of the power steering pump.

Prior to complete failure, you may or may not have noticed a slightly higher idle and a very slight roughness to the idle, some people may not notice this. The mileage will also have dropped by about 1 mpg, but again, a lot of people don't pay that much attention to their gas mileage and a 1 mpg drop in a car getting 35+ mpg is hardly noticable.

If you had a newer Saturn with OBD II, you would have gotten a P0507 code.

This does seem to be a bigger issue with the newer Saturn SL/SL1 engines, maybe the older ones used a metal backed gasket, but the newer ones used a fabric gasket with an RTV bead in it, and it didn't hold up very well.

 

cool i will check it out thanks

 

would that intake leak sound like a whistle when given gas and cause the engline to stumble and lose power?

 

Replaced intake gasket....still stumbles at 1500 and loses power. Firing order is correct please help

 

Compression good
All cylinders getting spark
Timing is correct
Fuel pressure steady as throttle opens.
No check engine light
Cat and exhaust system flowing freely
I'm stumped, it ought to be running great

 

This shouldn't be a problem, but are the brakes dragging ??
