need serious help
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

If you rev the engine , what does it sound like?

Well when its in neutral it sounds fine if I rev it hard it bogs out and when its in gear as soon as I let off the clutch and give it gas it dies

Now I have also replaced the fuel pressure regulator and and tps and found out it doesn't have an maf sensor so I have no clue what to do

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.

Fuel starvation. Bad pump.damaged crushed or kinked fuel line check fuel pressure as well as fuel flow also there is a fuel screen / filter in the tank.:unsure:
