skyline gts25t r33 sluggish

[ivecoman]

Recently my skyline has been lacking in performance.....I have had a couple of opinions from different mechanics telling me that the constant vibration is caused from dirty fuel clogged up in the fuel sytem or my coil packs/spark plugs may be faulty. You guys have probably answered these questions a thousand times over but if you have any advice as to diagnosing this problem it would be a great help as i would rather do the maintenance myself rather than going to a mechanic who will rip me off....

Thanks

Nick

PS. I have recently had service done on it fuel filter, oil change etc however this solution didnt help

Have you tried resetting your ECU/Runnig diagnostics on it?

Also look at getting your injectors flow tested and cleaned.

Check spark plugs condition/gap.

I'm having mine looked at at Ice Performance....I would suggest you get it looked at by professionals, just in case it could be serious and you over-look something

So is it sluggish or running rough/vibrating?

If it's just a bit sluggish, and this has only been apparent the last couple of months, then it's probably just the summer heat.

Wait for autumn and see if it gets better.

Is ICE closer to UPI or RACEPACE?

Im unsure cos im from the western burbs, but have been to both

if you put the foot down and it slugs on, like it has no boost then hits boost its most likely your plugs, get some platium ones or copper ones and close the gap a bit, to like .8mm

get your plugs changed and your fuel filter cleaned,a nd then get it tuned.

Just a thought, if you have a clogged up fuel system your car could be running sluggish because your ECU has detected knock and has retarded your timing. Not being a mechanic i am not telling you this is the case just a suggestion. I know when i had knocking/pinging issue in my R33 the timing was so retarded when i took it to the Dyno i had lost 40 rear wheel horsepower.

My car is slow in this damn heat.

Yeah i have been told by a number of mechanics at work that the fuel system could be clogged up with crap...i tried a fuel system cleaning solution however that did F@!K all...first of all i will be changing my spark plugs...failing that i will probably take it to ice performance in cheltenham.....
