4agze

[pauly]

car uses lots of fuel, runs shitty, ummmm thats about it i think

[Mr Revhead[RL]]

if your knock sensor has been glued, its f@$kED

replace it.

 

if it was plugs and leads itll run worse under boost, ie higher revs than below 4k.

 

is the o2 sensor u got compatible?

[Mr Revhead[RL]]

this is a MAP 4agze?

 

if so ITS YOUR KNOCK SENSOR!

GET A NEW ONE!!!

 

get it?

 

if its an AFM one, itl lbe something else as well

[pauly]

its a AFM and do u know how much is a knock sensor is its $250!!

um but doesnt knock sensor ONLY effect the engine when it runs over 4grand>>??

oh and do u have MSN?

Um o2 sensor is perfect match

and not sure what else

help,.....

Mr Revhead's right, replace the knock sensor.

 

 

they generally work under 4 grand to control ignition timing, retards the ignition when detenation happens, if the sensor is sending the wrong signal the igniton timing will be being retarded, so it'll be gutless and be using heaps of fuel.

 

also check for airleaks between the AFM and the throttle body this can also cause the engine to drink heaps.

[Mr Revhead[RL]]

from our brief mn convo (sorry my spare 20v motor arrived :ninja: ) i learned his is an AFM 4agze.

if thats the case the knock sensor wont be causing those symptoms, unless the gluing is causeing it to send a f@$ked up signal. i run my AFM 4agze with no knock sensor and while itll only run the base timming and is prob costing power, it actually runs fine.

 

so yeah start looking ofr vacuum leaks etc

[Jono]
