Ok I've got the I6 a few weeks ago it started idleing really bad and I could still drive it but I could barley hit the gas if I hit it to much it bogged out and now I can't even get it to go it starts it idles but when I put it in gear and let off the clutch it dies so far I've replaced the fuel filter, distributor, plugs, injectors, I've hollowed out the cat, and replaced a few vaccume lines and it idles a little better but still not driving. Any ideas

Check the map sensor, it should be on the passengers side firewall
Check the vacuum line for breaks etc, then with the engine running pull the vacuum line off, it should stall the engine. This is a quick test, if its working it should drop idle speed quickly when you in hook it.
