R33 Gtr Running Rough And Rich

[den15b]

Hi

Just purchased a GTR R33. I was giving it some stick the other day and it backfired and after that it wouldn't idle good, I could not really drive it to move it off the road because it didn't have any power, anyway, I have checked coil packs, spark igniter, AFM's, plugs and still can't find the problem. My next thoughts are, could the timing belt have skipped a tooth, it runs like it is running on 3 or 4 cylinders, while the car is idling, I unpluged coil packs one at a time and found that the front cylinders aren't burning fuel (no difference in idle), it idles with plenty of black smoke (rich) coming from the exhaust and the front cylinders are wet. Has anyone witnessed this or has someone had a car that skipped a tooth on the timing belt? Also, does the RB26 bend valves when timing goes out via a skipped tooth? I have done a compression test on each cylinder with the results of every cylinder being the same PSI whilst cold, it also holds the compression. The cars timing belt was changed at 70,000, it has now got 120,000, it seems legit since I received log books with the car and everything matches.

Any advice would be greatful.

It backfired, now it has no power? High chance of an intake leak somewhere near the 2 front cylinders causing your problems...

Well guess what? you were right! took it to Advan Performance Centre in Auburn, they found it straight away, however, all of last week it was at Castle Hill Exhaust/Performance where I had my VE SS worked (332rwkw) on (spent $12,000 on it through them, now sold), it looks like Skylines are beyond them, they had it for 5 days and could not work it out, I even told them to check the cooler pipes, they told me it would'nt be that, plus they left me with a nice dent in the passenger door, "thanks Dave, your an ass", anyway, I want to give the boys at Advan Performance Centre a big thanks, and to Dave at Castle Hill Performance a F$%kyou, all you did is screw me around the whole of last week, telling me you can't find the problem, you don't have time, you are busy, all I can say is, you don't give a shit about existing customers and a nice way to do business, you wont be seeing me again,
