These are known for spark plug issues and ignition coils going bad. Also the spark plugs are very difficult to remove and sometimes break which requires special tools and knowledge.

P0305 is cylinder #5 not firing. P0300 is random misfire which the computer cannot determine which cylinder(s) are misfiring. Check to This will make a lack of response or no power when the pedal is depressed. P0300 can be caused by spark plug wires needing replacement if equipped.

Check to make sure the catalytic converters are not restricted or plugged. This will make a lack of response or no power when the pedal is depressed.

Check for restricted exhaust creating excessive backpressure. The converter is probably plugged up. This will cause a severe loss of power & lead to further engine damage if not repaired.

I hope this helps.

Real good chance the throttle valve cable and linkage from throttle to top of linkage is seized, or seizing and needs lubrication. You'll have to remove battery to see it good under battery tray, and look for the piece of linkage on top where shifter linkage attaches.It needs to move freely. It also regulates your shift points as well, when passing etc. If you push gas pedal hard, it will begin to stick in lower gear longer (revving) before it shifts up, and will downshift hard as well when slowing to stop. Gas pedal will feel stiff, until you get it freed up. Try penetrating lube like WD-40 first to get it freed up, then spray white lithium grease or similar on it after. Do not try to remove nut holding it on, and remove linkage, just leave it on there and keep working it until it will move a full sweep back and forth freely. If you remove that piece of linkage, shaft will drop down and need to remove pan etc to fix it. If you need a picture, let me know, I have one from past experience with same.
