May have a handle on my hesitation issue

[Kevin]

I took the car on a 20isj mile drive this morning. Drive it easy for the first 10 or so but went wide open in 5th a few times and it ran fine, this was on the highway so 65 to 80ish mph. Got off the highway sat at a light for a bit, went wide open in 1-3 and the rear end broke loose on me on the 1-2 shift. Slow down to 60 or so then got back on it in 5th and t started missing again, stated in it a few seconds and sure enough a service engine soon light came on the dic. So I backed off, and it went away as soon as I did. A few miles later a friend of kind with a Ferrari passed and I sped up to follow him. Right around 3000 rpm the service engine soon light came in. I guess this is a good thing as I have a code to work off now. Ill keep you guys posted. I'd pull the codes now but I don't have the groundin plugs at cars and coffee and I'd prefer not to pull the codes in a parking lot at a show anyway. It can wait till I get home

I'm thinking a LEAN code.

Had exact same issue. Turned out to be a failing secondary solenoid - intermittent. Good luck Kevin. Hope it's something ez. Also check and clean map line and position so oil doesn't collect in line.

I was thinking either running out of vacuum, though Marc checked that at Carlisle or running out of fuel

I think it is Kevin with the hesitation issue. I have hesitation sometimes but that's when I pee

pulled the codes, code 16 dis system fault line circut. so it's either the dis, the wire from the dis to the ecm or the ecm....which means I need to replace lots of expensive parts and hope for the best

could just be the connector at the back of the DIS.
Let's hope.

either way I still need to remember how to pull the plenum and go after this. I haven't personally done it in probably 10 years. I'm a little rusty
