Posted April 22, 201311 yr comment_421269 I would like to start off saying thanks for all the help from the previous posts. It has been really helpful, and I love you guys for it. My 78 is sluggish when accelerating when the motor is warm. I guess it isn't getting the right amount of fuel/air? I noticed today when the engine is cold, and the automatic idler kicks in. The car has much better response and power. I'm guessing this is because of the increase in fuel. It's mostly sluggish between low RPM's to medium RPM's when the engine is hot. It seems to help when I petal the gas before accelerating. Is my problem the fuel being too lean? Is my TPS not configured right or broken? ThanksNote: The car idles around 1200-1500 RPM's. It has a slight miss at those RPM's, but when you speed the motor up it doesn't.

April 22, 201311 yr comment_421273 How hot is hot? 180? 200? 210? Don't know FI so I better not try to diagnose it. Hotter air to the intake means less power. On the other hand, my 240 makes more power when it's thoroughly warmed up: 3700 rpm = 78 mph (AT in high gear) when cool (but operating temp) in the morning; 3700 rpm=84 mph on a warm afternoon.

May 8, 201311 yr Author comment_422867 Sorry for the late reply, I've been gone on vacation. I figured out the problem. The pickup coil wires from age fell into. So I order a new pickup coil and it works great now. Thanks for the help.
