Okies, I'm having some probs with the EL, and am hoping for some suggestions...
Basic problem is that recently (past month or two), I have been having problems with a pretty average idle (misfire). Also (more importantly), under about 2750rpm, it seriously misses. Once you get to 2750-3000rpm, it takes off (feels like a twin-cam when the second cam kicks in).
Now the odd thing is that this is *much* worse when cold. Its still apparent, but nowhere near as bad when warm.
The car is running GT-40p's with 1.7rr's, with pacemaker extractors (rest of exhaust is yet to be completed though). Top-Gun leads, iridium plugs, new accel coil. dizzy rotor and cap are 2 months old and look fine.
MAF is standard, but clean. Timing is roughly 33, running bp ultimate.
The fuel filter definitely is due for a change, but is being a prick, and I haven't been able to get it off yet.
I'm looking for ideas. I'm yet to check the TPS, but with the miss, am not hopeful that its the problem. My only other vague theory at the moment is that the injectors are clogged slightly, and at lower duty cycles are tending to "drip" rather than spray. I figure this might also explain the improvement when hot (the manifolds will start to evaporate the dripped fuel). I'm starting to think this might be more of a fantasy than a thoery tho
But it would make a nice excuse to buy new injectors and a matching maf :)
So, does anyone have any ideas from this rambling ? Plllleeeaaassseee !
Low-end misfire and Idle ?
