My truck idles fine, goes down the road fine but when you are in a parking lot or when you slow down from going normal speed for ahile it will bog down like its going to stall but never does!!! Ive done everything, this is the only thing i can think of that i havent replaced!!!

Might have something to do with the cam you have. Probably just a normal function of your cam. I'm assuming it is hotter than a stock cam.

Possibly... Most of the time with at bad coil, you'll experience an uneven missing.

Does it dip down then jump back up or does it stay there at the low rpm? It if dips and recovers, it might be a vacuum leak. Maybe IAC? I don't think the coil would be the problem but it might. Maybe even check fuel pressure, it might be dippin pretty low at that particular time.

Does a 1995 even have a IAC? I was thinking you had a vortec.

1995 was the last year of the older TBI. Then in 1996 they went to vortec. It has a IAC.

I knew that already. I changed my verb tense in the post you were responding to so it won't be as confusing. I was assuming it was a 1996 or later due to the body styling. I was just asking whether or not a TBI even had a IAC. I remember when the vortec first came out. My dad was one of the first in line to get one. I remember compared to our 1994, it was a monster. We thought we were the ****. Whoopin the dodges and smokin those 80's camaros. It seemed like a sports car at the time.
