I have a 99 Ranger 3.0L That will idle real rough when/if it starts. It will crank but wont start sometimes. CEL codes read P0176, P1132, P1152.

Could this be caused by a bad IAC Valve?

Thanks for your help.

 

Sputters when driving, loss of power.

Suggestions?

 

I have a 98 and kinda the same thing, mine has never not started, but i just gave it a tune up ( Plugs, wires) and it seemed to help a little but im still nto happy with it. It just seems to shake teh whole truck. I have no codes but it drives me crazy, what to do??

 

Plugs, wires, clean your MAF, fuel filter, injector cleaner

 

Its your egr valve.

replace that and the dpfe sensor and your good to go.

Its about $100+ whatever your tax is where you live..

 

Thanks for the reply. I will Try That.

 

Thanks for the Help Mark, Running Great now.

 

What did you replace the egr valve, dpfe or both at the same time?

usually if the egr is bad the dpfe is bad to or its one or the other. I replaced my egr valve it ran great for a day and then it threw the code again the next day and I replaced the dpfe and havent had an issue since. Its hit or miss with these things so its just easier to replace both at the same time, just not easy on the wallet.

 

I replaced both. The CEL Light came back on today, but i havent checked the code(s) yet. It cost me about $115 at auto zone for both.
My Next step is going to be replacing the plugs, and wires, though the back ones look like there going to be a pain to get to.

 

yeah the driverside last one by towards the firewall is a bit fun.
