ok, unfortunately i have absolutely no idea what you are talking about.I played around and ended up with 20 degrees of timing at idle set in the handheld and it starts easily when hot. Due to the insane sensitivity of the IAC it's either IAC of 0 and the computer retarding the timing to around 18 degrees with a nice idle, or IAC of 50-60 with full timing and a rougher idle. I went with IAC 0.
1. you manually advanced timing to 20 degrees . the rpm increased and it still started easily when hot?
2. you connected the computer and it retarded tje timing 2 degrees to 18 and it idled at the same rpm?
3. you changed something and it idles like crap?
Timing is 20 at idle (18 in practice)' date='[/quote']
I is ether 18 or 20 . which is it?
Ok' date=' taking it for a quick ride to beat the weather, there was a marked improvement. A slight tumble when tipping into the throttle,[/quote']
It sounds like your accel pump is squirting way too much fuel . the accel pump is the last thing you should change . go back to the stock one and see if the stumble goes away.
put it in second and rev it until it stops revving and tell us how far it revs.but a quick half-throttle flashes the converter and results in tire spin. At 2/3-3/4 throttle it really screams, zero to 40 in about 2 seconds (or damn close to it), with 50 and the overdrive kicking in before I can shift to 3rd, all without going but a tick beyond 5000 RPM. Near or at WOT it rumbles and sputters a bit and won't rev much at all beyond 4500. No power and very sluggish acceleration.
So, what am I looking at when scratching WOT? More fuel?
