its extremely hard to diagnose over the inernet bud,

can you get it onto a dyno?

[Shmee33]

yeah ill take it to morwell tommorow and have it dyno'd so i can see what's wrong i guess.

i think ill try the fuel pump first then ill take it?

i really wanted to get the problem before taking it to get a dyno

thanks for the help anyways and ill post whats wrong with it when i find out tommorrow.

Nobody has mentioned cat converter could be blocked? I mean it's unlikely to a certain degree, but still.

Sounds like one of the many sensors is dead, the AAC is probably gunked up hence the bad idle and it probably needs a tune for the mods that have been done to it. All of these combined result in the issues you are seeing.

cat converters are the most shitty things ever, iv bought 2 new ones in my life time and they cost about $150...

there only for the enviroment arnt they?

my oxy sensor is old and the plug has 3 wires going into it and one is just sitting in there.

the blue wire going into the oxy sensor looks damaged but would that be the reason?

whats the blue wire for?

Actually they are a brilliant invention, without them we would have alarge amounts more smog and a large increase (im talking 20% of the pop) in asthma and breathign problems.

However if your cat is the original and 20 years old it is probably not doing anything anyway so no real harm with removing it.

The car is having a flat spots and jumping while reving out. Maxs out at 5k. Getting the tune done on monday I'm guessing r and r mode?

[paulr33]

go see a mechanic

and by jumping when revving do you mean the needle is slipping or moving freely ?

could be clutch slip if thats what you mean - what clutch?

[Shmee33]

It's not the clutch, I got a new one put in 6 months ago. Iv cleaned everything or replaced it besides a tune and afm check.

Drop the cat and see what happens, I reckon the guts of the cat will fall out when you remove it.
