What are some signs that one or more of the injectors may be starting to fail. I have increasing difficulty starting it. It turns over well, but it's just taking longer to start. (There is no upshift arrow light...yet. And I still have the bolt holding my HB on.) Other symptoms that I'm having are:
1) A consistent "miss" under moderate to hard acceleration. This generally happens just after I press on the accelerator.
2) An occasional "miss" under low rpm acceleration. This happens between 1k and 1500 rpm under moderate (at most) acceleration. The engine is under a heavier load than if it were to downshift.
It is always as if the engine completely stops for an instant and then continues on as if nothing had happened. I'm not getting any codes relating to this. And the cylinder test passes too. I'm starting to think that it could be related to a fuel issue where I previously thought that it might be an ignition issue. I've put on a new fuel filter, but it didn't help. If it were the fuel pump, I'd have more problems (specifically at WOT) than I'm having now. There doesn't seem to be any fuel "starvation" issues at WOT and high rpms. So that leaves the injectors, or maybe the MAF, TPS or IAC. The latter 3 would have other indicators that would presumably point me in the right direction. Any other thoughts would be greatly appreciated. Thanks.
