Its a 98 2.5 ranger.code p0171.checked psi with a tire gauge(not sure if its correct)was at idle with 32psi.

 

32Psi seems kinda low whens the last time you changed the fuel filter?

 

Any idle or top end issues ? Fuel filter would be a great start.

 

Itll idle up and down sometimes and sometimes with ac on coming to a stop it almost dies.in 5th it dont like to accelerate even at 70

 

I would say you have a vacuum leak. Check all your vacuum lines and if possible ( you can carefully check using carb or break cleaner sprayed around the intake at each gasket to see if the idle changes at all ) the intake / plenum gasket(s) . There is a outside chance the MAF could be the issue but not as likely. You can get some MAF cleaner and clean it if you want .

 

I just changed the intake gaskets.upper and lower tb iac and egr when i changed the plugs.

 

Sounds like you've got it covered. When did the problems begin ?

 

I only had it for a couple weeks.has never had any low end power even with the po.if i start off going up a hill i have to rev it up and kinda ride the clutch till it starts moving good..but it seems to run fine till it gets to normal operating temp and sometimes when it is at normal it runs good.

 

Try cleaning the maf ( maf cleaner only ) and see if that help.
