95 Eldorado running rough

[tommysmommy2003]

Hi, Everyone!
I bought this car a month ago with 100,387 miles on it. I just started driving it. When I drove it home a month ago, it rode pretty rough as well as ran very rich. We have replaced plugs and wires. The gas milegae still reads an average of 10 mpg. It "shivers" sometimes when I am on the gas. I did pour some Fuel Inj. fluid in it yesterday. After 1 mile that car started acting like it wanted to stall, but snapped out of it. It just acts weird when I am on the gas. It spit out about 6 codes: P052,P109,IO22,IO52,S036, S044
I looked them up, first of all it Greek to me, but the discription doesnt seem like it is anything crutial. Any advice would be appreciated.
Thank you

probably an FPR
pull your intake cover and see if you smell fuel...

I will see if I can do that tonight. I found out that I may have the wrong spark plugs in there also. I was told that I need the AC DELCO (spell) and we put the Platnuim in it. I was told that the platnum will not get hot enough.

Hi, Sorry for the late update. I took her to the shop 2 months ago and it turns out that one of my coil packs had to be replaced. I was running on 6 cylinders vs all 8. Right now I am getting 18.4 mpg, wish it was better, but has doubled.
