Cool 95 v6 mustang bogs down when it gets warmed up

I have a 1995 3.8 v6 mustang that acts like it bogs down under acceleration, especially when it gets warm, The cars engine runs really good except when its warm and when giving it gas to accelerate. Does anyone know where I should begin to get this fixed? Thanks to all

Re: 95 v6 mustang bogs down when it gets warmed up

how many miles on the car?

honestly i'm new to the mustang world, but one thing i would say would be injectors sticking. not sure if that would be it or not, otherwise i can't think of anything, someone more knowledgeable should be along soon

just thought of something else right before i posted... maybe your fuel pump? you could do a pressure check on that to make sure its supplying enough fuel under acceleration. but like i said i'm new to these engines. maybe also worn spark plugs/wires, other igintion stuff thats usually replaced, that was the problem on my last car but it wouldn't run good at an idle either...

Is it throwing any codes, as in do you have any check engine lights on?

Re: 95 v6 mustang bogs down when it gets warmed up

Hey Guys,

Thanks for the feedback, I bought a OBD II scanner and the codes it pulled are

P 1131
P 1151
P 0171
P 0174

155,254 millage
3.8 V6
I have put a new MAF and cleared the codes. The check engine light went off, but now it seems to bog down at first and then rev up. Also when you drive it about the same time the gauge shows to be getting hotter. When it rev's up I can hear like a whistle in the engine compartment. Any Idea's

Re: 95 v6 mustang bogs down when it gets warmed up

well i looked the codes up on google, all 4 say the engine is running to lean. I looked around and one suggestion was a vacuum leak which i thought could be the whistle you heard... (again, i've never messed with codes or the v6, just throwing possibilities out there)

locating the source of the whistle might help.

So you think it might be a vacuum leak, that is kind of what I was thinking. I noticed today that the rubber hoses I think are the vacuums are deteriorating, you think that it might be that or the egv valve?
