Bought a used '04 VR6, 5 speed, 96k miles - I get the stutters when I accelerate, its particularly noticeable in second gear, in the other gears the engine generally feels a little lean. The problem is nowhere near as bad after adding a can of Seafoam but comes right back again with a fresh tank of gas. The air filter is new, I'll check the plugs and leads and clean the throttle body this weekend but my gut feeling is that I have dirty injectors or a clogged fuel filter. Anyone else had this problem?

How much do new injectors cost and how easy are they to replace? I good with a wrench.
How much should a fuel injection service cost?
Where does the fuel filter live?

This is a nice car, it should absolutely fly when I clear this problem up.

Is it a ticking? Have you changed the timing chain on the car yet?

Also, if you go to do the timing chain, you may as well do the clutch at the same time.

The long block was replaced at about 70k so the timing chain and pumps are all pretty new. I would imaging that all the original ancilliaries were bolted back onto the new block. Definately seems like fueling issue, 2nd gear is where the greatest fuel demand is.

Do you know the timing chain was replaced or are you guessing it should have been?

I'd suggest you find your local VR6 specialist and let them see and hear what it's doing. ;)

I removed and cleaned the throttle body and the MAF, that cleared up 98% of it. Pretty easy job really. There's no need to unclamp the bigger coolant hoses like some of the web postings tell you, just the small one that supplies the throttle body (presumably it keeps it from freezing up). Ran a couple of bottles of Seafoam though the fuel too. The check engine light also came on before this work was done; had the codes pulled, turned out to be a leaky vacuum hose at the rear of the motor. That explains the lean simptom. Special order part, empty wallet...
