Just some quick questions for the experts out there....
Finally got around to tuning the '86 T I just bought. I've noticed that at WOT the cars skips a little bit. My first thought was ignition related, or possibly fuel related. I'm running 100 Octane and around 19lbs boost.
I hooked up Turbolink and took some idle readings and cruise readings. I tried to do some WOT readings but its almost impossible in this weather unless I was on the freeway doing about 70. O2 readings bouncing around like normal and seems fine.
I then checked the fuel pressure and noticed it was set at 50psi with vac off! I turned it down to 43psi or so and took it for another spin. It started to snow just a little so I couldn't tell if it had any effect. Never saw any knock except for a little on wheel spin (at about 50mph heh). I won't be able to tell much until I can WOT, but I'm assuming the 50 was way rich. Could this lead to the skipping at WOT I had experienced previously?
I've noticed the idle bounces a little and even more so now that I turned the fuel pressure down. Looking at the numbers at idle, I noticed the TPS is at 0.47 (a little high but within range) but the IAC is steady in the mid 50's. Would this cause my idle to bounce around like it does? I assume the solution is to adjust the IAC to 20-25 and then adjust the TPS accordingly.
Thanks,
