Re: 03 impala idle issues

said by Anonymous_:

Fuel Pressure Regulator failure going to be 300.

That's really not bad all things considered.

'01-'05 Impalas are tanks. They are great engines as well. My 2004 currently sits near 180k and still is running like it was 50k.

when equipped with the 3.8 you could pretty much burn kerosene in them!

I use 91 octane 87 engine knocks too much when idling and is much louder when running

everything works good now

This isn't a good "fix".

The engine is designed to use 87 gas. It should use 87 gas.

You may have bandaided it for now, but leaving a failing/failed part in there WILL cost you more in the long run.

knocking issue is a gas issue . there is nothing else wrong with the engine as I had it checked out. when I had the fuel regulator changed out.
Says it can run 87 or higher anyways .

mileage was 9MPG city-15MPG highway with the bad fuel regulator (before it failed I was getting 17/23mpg)

I have the 3.8L
I suspect the PCM was modified by a previous owner. Since I can run the high and low beams at the same time (this can be done by modified PCM settings. )

No, but the BCM does.

But as far as the headlights, it's just one extra wire and a relay for the switch. It's incredibly simple. No actual recoding necessary.

Yeah, but the OP's questionable deduction referred to the PCM.

Right, which is why I was pointing out that he would be incorrect in that assumption.

the knocking issue can be plugs and wires too.. if u havnt changed your plugs and wires yet, especially if u seen sparks i would...its very cheap like under 100 bucks and is part of regular maintance.. probably get rid of the knock too.. i had a ford explorer that would start to knock when the plugs started to go bad...

and before you go swearing at the back 3 plugs, park it on flat ground, undo the front engine mounts, put it in neutral, rock the engine forward, brace the engine with the second hole in the engine mount. that way you can change the rear 3 plugs without any trouble.

Dirty combustion chambers with carbon deposits can cause knocking too. They should clean the fuel system and intake system with a carbon remover like Seafoam.

The fuel injection pressure regulator on a 3.8L engine is a $50 part... It's located right on top of the motor and takes about 10 minutes to replace... No way that's a $300 job...

I wasn't sure of the price, I just meant as far as repairs verse scraping the car (which he has hinted at multiple times)

I have an '01 Impala LS and it's still going strong... I've had my share of issues with it over the years but all fixable... I did have an idle speed issue last year with symptoms similar to the OP... Plugged in my code reader and got a code for the MAF sensor... Bought a re-manufactured MAF for about $100 and replaced it (a 5 minute simple job) and all is good... Another part that gets dirty or goes bad is the IAC (idle air control)... You can clean it or buy a new one for about $40... Also simple and quick to replace...
