Engine Tech / Idling problem when cold ( '91 5.0)

that is a stock 86-88 cougar engine. look at all the brackets and what not. He has a stock 150hp engine, not the 200+ from a mn-12 cougar or mustang.

Like I stated earlier, the engine was pulled out of a 1991 Cougar with an auto tranny. And I can tell you from driving it...it has more than 150hp.

My straight 6 had about 140hp, and this thing is way more powerful.

Oh, and thanks Brian.:D

The fuel pump is an electric I picked up at a napa store, using the ractory hard lines, with FI hoses to connect with.

I haven't got it reffed yet, but it will be streetable.

I'm not sure what the S.O 5.0 is?

The motor came out of a '91 Cougar.

Thanks so much for the quick reply and info. I will check the tps for proper voltage.

I swapped a '91 cougar 5.0 into my CJ. It runs like a champ when it's warmed up.

The problem is it doesn't want to idle when it's first started. The idle seems to go up and down, then it will idle really low and die.

Any tips would be great.:D
