TFI Module Revelation

[Chevyguy]

I just finished stage 1 of my failed inspection repair. Yesterday I swapped the new wells TFI module in, and replaced the plugs and cleaned out the TB. The plugs looked fine, only about 20k or so on em, kept them for emergency. I found out you have to rotate the dist to remove the TFI, and I had to use that funny ford ignition wrench I got years ago cus the screws were so deep in there.

I fired it back up and forgot to mark the tdc on the balancer, got some chalk and fired it up again. I reset the base timing to a hair under 10 deg up from 8 as it was set, ok I still run 87!

Noticed a more stable idle, and now it pulls MUCH smoother when you lug it down in the 1k to 2k rpm range. The plugs were clean, and the TB was not too dirty either. I thought a TFI would only hard fault and make the motor stall or not run!

Of course this was the original Motorcraft unit with 125K miles, no recall

Best $30 ive spent so far
