Hi Guys, in desperate need of help with my R33 Series 1 1994 Skyline Gts-t.
i live in adelaide btw.
ive tried everything to fix these issues, here they are.
Work done:
- 3 inch full exhaust
- front mount
- pod filter
- earthed solenoid
- after market BOV - Plumbed back in
Symptons:
1. High idle at stopped after car is warmed up - 900rpm
when moving between 10km-70ishkm and clutch in or in nuetral car idles around 1500rpm
when moving above 80ishkm and clutched in or in nuetral the car idles around 1500-2000rpm
sometimes the idle will hunt between 1000-2000rpm also in same situations, always varying and intermittent..
2. Fuel economy has basically halved.. used to get to and from work on just over a full talk, now its around half a tank a day!
3. Powerloss at some points - intermittent, dynod it last week drew 178kw at wheels.
but the issue is mainly when driving over 10kms/h.
Things ive done:
- Replace coil packs - spit fires
- Replaced spark plugs
- checked voltage to each coil packs and disconnected packs individually while sitting at idle - ok
- cleaned wiring loom earthing point
- replaced MAF - genuine
- electrically tested idle controller (brown plug 10ohm) (purple plug 20ohm) as specs say, also cleaned idle cont - springs ok
- tried adjusting idle screw all that type of stuff.
- checked if cold start valve letting air through after warm up - no air
- checked for air leaks
- replaced throttle position sensor - genuine, set to .45v
- cleaned out throttle body completely, adjusted stop screw, adjusted accel cable to have a little slack as its meant to, checked for gap in butterfly - no gap.
- had a recommended mechanic look at it - nothing unordinary found
- had the dyno specialist look at it on consult, fuel mixtures seems all ok, pulled ok on the dyno at the time conviniently.. and he couldnt find anything unusual either (car was still standing still tho)
- new o2 sensor - kudos
- no faults found on the nissan consult
- have swapped the BOV with a known good stock BOV and no difference.
theres probably more stuff ive done that i cant think of at this point but if i do remember anything else ill add it to the comments section
replacing and these parts and checked stuff ect, has 50% fixed these problems which has still got me to this average stage of fixing these issues, as well as fixing other issues.
this is killing me price wise + petrol wise.. any suggestions would be hugely appreciated! Thanks - Tim.
