1999 1.8 dies when I whack the throttle.

You guy have me a good hand with an earlier problem with m '99, hopin you can help me our here...

The pipe that connects the cat to the res spit at the flange to the res...then started to get this hesitation when I whack the gas off idle....I just replaced the pipe from the cat to the res, and lower 02 sensor and the hesitation remains...check engine light is not on....makes the car a PIA to drive on the commute.

Any help is greatly appreciated,
T.

Todays update...to check for vacuum leaks I started the buggy and the ran propane around all the connections around the intake...the RPM's didn't pick up at all so I'm thinking I don't have a vacuum leak.

Where is the fuel filter in this buggy? Wondering if it's plugged and not letting enough in when I whack the gas.

Looking for suggestions.

My 1.5 Stuttered on full trottle and got worse when warm - It was the coil packs


Might be worth a try ?
