Greetings from Prague.
So - in case it doesn't show up at the bottom of my post, I have a 2003 Toyota LC120, 3.0L diesel, standard transmission, about 150,000 km. I bought it about three months ago - it has spent its entire life in Prague. According to the records, the injectors were replaced in 2008 by the local Toyota dealership, no doubt due to the known injector issues.
I've replaced the air filter, and will get around to the (single, under the hood) fuel filter soon.
I've read about all the carbon build-up in the EGR, manifold, and elsewhere, and will get around to cleaning both of those (have ordered several cans of Wynns EGR3). Am also currently running through a bottle of STP diesel fuel system cleaner.
Here's the problem - when letting the clutch out, I have to make sure the revs are up around 2000 before fully letting the clutch out. If I don't, the clutch engages, but it stays at idle speed for a few seconds before the power suddenly kicks in (doesn't matter if I floor the accelerator - no change in speed for several seconds). I then have to put the clutch in again, rev the engine, and try again. The same thing is true for second gear, if I shift before I have enough momentum and high revs, the engine just seems to idle. I can floor it, and nothing happens for several seconds. People behind me are getting a little irate.
I thought perhaps I have a clutch problem - but if that were the case, I'd be able to rev the engine when the clutch is engaged, and the vehicle wouldn't go anywhere. That's not the problem - the problem is the hesitation before the throttle responds.
So, I'm going to change the fuel filter and clean the EGR and manifold. Can anyone think of anything else that I should definitely check? I'd hate to go through all that (even though it needs to be done) and still have the problem. Is this indicative of the injectors needing replacement again already?
Thanks,
Clive
