hey guys..
just want your opinions on a problem i'm having..
basically my set up is a pulsar vzr sr16ve, the only mods are a decat pipe and thats it.

after driving two other vzr's, i've noticed that mine does not seem to pull as well as the other two, taking off, i'd say mine is quite slow compared to them and the revs dont seem to go up as fast as they do.

i do think though, that my clutch may be on its way out.. would this be a cause of it? or could it be more sinister engine wise? any thoughts or if yous want me to explain it a little better please let me know! thanks in advance!

tuning..... ecu..... timing...... compression test.........just throwing things out there that you can compare.

Well you could pull the motor and send it to me lol j/k... Have you done basic tune up??? and also a bad slipping clutch you would rev faster but go nowhere

dont have the tools myself to do any tune ups or diagnose any problems.. how can you diagnose the ecu?

damienga15de@ho

Hey will, iv read somewhere think it was on the aoc that a de-cat will cause the car to not pull so well from start/low revs.

I've a de-cat and it pulls as well as it always did! You gotta do the basics first to illiminate,change,plugs,distributor cap,rotor,check ign leads,change oil,air filter renewal!
If it still persists do a self diagnostic,its very simple,pm me for how to or txt me ya have my number!

Dub_Vzr

donal you have a text!

the only thing about my decat pipe is the diameter seems to be quite small in relation to others.. would that make a difference?

also i have done the sparks, oil, air filter etc..

Try pushing instead.

Dub_Vzr

anyone else any suggestions/ideas?

oliverr87

check your timing

Dub_Vzr

was thinking that myself.. would it make much of a problem if it was changed?!

Dub_Vzr

lucino done a dianostic for me and we got a fault code of 45 - injector leak.. any one have any ideas what this could be? we took a look at the injectors but there doesnt seem to be any major leak..

evldan

Have them cleaned and flow tested maybe, at worst it can't hurt! (except maybe the wallet)

damn.. is it really a big job? would it just be cheaper to get a set of new injectors? lucino also said what if it wasnt the injectors? i know it reads as an injector fault, but could something else be tricking it in thinking it was the injector?

evldan

It would be waaay cheaper to get cleaned/flow tested than buy new ones! just price up some one local who does it (might be cheaper around your way, not too many people that clean side feeds around me)

Dub_Vzr

will have to look into it, but i think i'll take a safe route and try eliminate the simple things before i go and try anything thats gona cost be an arm and a leg..

just wondering, if it says its an injector leak, could it be someting else thats tricking it into thinking its an injector leak? lucino mentioned that to me earlier but i'm not sure.. what you guys think? could anything else be wrong but show up as an injector leak fault?

i also dont know how long the fuel pump has been on the car, i havent changed it since i got it so i've racked up 20000 km's plus whats been on it before, could this be a cause of my problems? any help appreciated..

Dub_Vzr

right, i done the diagnostic test again and it only came up with 55 (normal operation) the 45 is gone.. any one any ideas PLEASE!!!

bazza1600

its probably set the knock code at some point and is now running off the knock maps, try resetting the ecu.

Dub_Vzr

nice one, to reset i suppose its just disconnecting the battery for a certain amount of time is it?! how long should i give it?

Honest Bob

I would just disconnect the battery and tap the brakes. That should draw any charge left. If you want let it set for 10 minutes and it should be good to go.
