i think i may have encountered the problem of why my car is getting 11 mpg. doing a little research i think my fpr could be leaking. did a tune up , new O2 which brought it up a little bit, tps and temp sensor. car got better but way off from where it was. i lifted the vacuum off the tip and seen a little fuel surrounding the bottom of the needle,not a lot but its there. i even smell gas sometimes but only at a certain spot. i dont know how thats even possible , i park at this spot at the park. i only smell it there tho , hell i thought it was just my mind. not a lot but its there and i can smell the gas in the vacuum line. i replaced my map sensor and my mileage drop way down. so i put the old one back in but noticed my car performs better with the new one. so i wonder why isnt this issue showing any codes ? so what do you guys think ? this problem is driving me crazy
FPR = $35. Just replace the damn thing and go from there.
Something that happens often with the MAP sensor is the car will run like crap and throw a code if you don't put the 2 or 3 o-rings back around the PCV valve. As to why you aren't throwing a code - my only guess is that it may be programmed out of the PCM if you have an aftermarket tune.
I would replace the PCV valve with an AC Delco (not an aftermarket!) valve - it wouldn't hurt. You may also have a vacuum leak somewhere.

Yes another one lol this is serious . To much money going to the gas pump. I thought you guys may know the answer . A impala shouldn't get this type of gas . I like the car but not enough to keep up with this issue .
There shouldn't be any fuel in the vac line so it looks like you found another culprit.
Also make sure the vac line is clean and dry when you replace the FPR otherwise it won't work properly.
You also said you smelled gas sometimes.
wouldn't hurt to follow your fuel lines from the tank to rail and see if there might be a leak..
And about the( what another thread post) it is better for you to keep your problem in one post so that others can see whats been done ,whats been said so you can hopefully be helped quicker and better by the members of the forum. Its not perfect but it helps
I did they couldn't find it . They did something to the computer and it increased it a little bit . I'm in the process of replacing a FPR from used impala engine . Looked just like mine to . Got it for 20 and he even gave it a warranty
i didnt know they went bad frequently. mines was fine the whole time for the past 5 years. the ac delco one in my area was 75 bucks. my local mechanic had one from doing engine swaps, so he keeps some of the parts from the last engine.
Yea I tried but currently having a hard time with that bottom nut. So I just left It on for now and will try to change tomorrow . I don't have the 75 for a new one now . I'll see how she reacts to this used one , I accidentally started the car without my maf sensor plugged in , is that a bad thing ?
