How to warm a cold-blooded Stang?

[JC6715]

Seems like my car takes forever to warm up. I have a really bad hestitation from idle, but I can power through it by givin'er more gas. This goes away once the car is finally warmed up.

We're talkin' having to let her sit and idle for 15-20 minutes for the hesitation to go away. Is this standard or is there something bigger wrong?

Thanks for helpin' this newb out...

You need to adjust your choke so that the butterfly is almost closed on start-up.

Sounds like a carburetor issue. I'm used to Holley pumpers, so if you dont have one, I cant help with that. My old '65 had a 289 with a Holley 600 pumper and I never used the choke(manual), even in freezing weather. All it needed was a tap of the gas pedal at most. My current '68 is the same way and still needs fine tuning. Just for comparison's sake...

I had this problem on my car, had a manual choke that wasn't hooked up, so I used to have to tickle it to keep it going for the first 20 seconds. Every time I would tap the accelerator to do this, it would almost stall out, but after my foot had left the pedal it would rev up a little and return to idling lower and lower. It was like it was very slow to react.

I just richened the idle up and opened the butterfly slightly so it idled around 100rpm higher but still richer as well. Seemed to help out heaps, came on stronger when driving too.

I have the same issue, thanks for the tips for the choke :SNSign:
I'll give it a try.

A supercharger will go along way toward getting her warmed up too ;-)
