Rpm Hunting At Idle

[TTA_PACE_CAR]

Don't know if this has to do with my problem but I discovered a minor vacuum leak in the hose going to the brake booster on the booster side. When I removed the line I noticed it had a strong smell of gas in it. I put a hose clamp on the booster side. At idle I did notice a variation of rpm when I pushed on the brakes. The brakes work fine so it is not affecting the functionality of the booster but maybe its an issue with the booster

So is the idle still hunting like it was prior to finding the leak?

IT WAS THE FUEL PRESSURE REGULATOR!!!!

Great! A fuel pressure gauge would have caught that right away. Well at least you have a bunch of new parts on the engine now

P.S. Put the stock MAF back on instead of the aftermarket piece.

No more hunting. Idle rock solid at 900 rpm

Always nice when you can fix the problem yourself, now Its time to spool it up

Just checking (bat), it could still be the Maf, parts house replacements are junk. you will have to get a Lt-1 maf and a translator, even if its not bad now its just a matter of time, like i said before change the fuel filter and post the SM after it has warmed up.. also if you have a stock chip you need to remove it and throw it as far as you can, replace with Turbo Tweak...

What is the correct Lt-1 MAF for our cars. Translator was easy to find, but not sure about the maf. Thanks.

You can use LT1, LS1 or Zo6 maf, the Translator will adjust to either
