You can buy or rent a fuel pressure tester from autozone. Unscrew the schrader valve on the fuel rail, screw on the tester, crank, and see what your pressure numbers are. But seriously, see what the cel says, there's likely somethin stored in there. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Does this mean I need a new MAF? and call it good? __________________ 2LT Rodriguez CA ARNG

Sounds like you have some vacuum leaks, a bad maf, and a bad precat o2 sensor. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

I question, oil has been leaking from the turbo into the intake...would that oil trash the MAF? It's been about a year since the install... __________________ 2LT Rodriguez CA ARNG

Yes. It could've coated the inside of the maf thus creating a faulty reading. Maf usually causes misfires from there. O2 causes fuel trim changing, vacuum leaks are unmetered and cause sensors to create improper readings and specs to the dme. I have extra maf here if you need __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

The aren't really that many hoses on our cars. __________________ 2LT Rodriguez CA ARNG

Each injector has a vacuum hose. They connect together and attach to the intake boot which is past the MAF sensor. The boots themselves can crack too. The PCV system has vacuum hoses in and out. Then, there is the vacuum line to the brake booster.
The intake manifold is a 2-piece system. You could have a leak between the 2 pieces.
A smoke machine is excellent to diagnose these problems. __________________

Also, if it has the fpr underneath the car, there's a vac line from there to the intake manifold as well. If its the m42/m44 setup, then the for is on the rail. Also, for the m4x, the fuel pressure should be around 45 static. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Parts should be here today, but a buddy told me a trick to see if the MAF was the problem... un plug it and turn it on... boom it ran. Plugged it back in and it wouldn't run... un plugged it again, and it ran... Of course plug and un plug while the car was off. My problem should be solved (fingers crossed) when I install the new MAF and pre-cat O2 __________________ 2LT Rodriguez CA ARNG

New MAF installed and car back to running... next up on my day off I'll install the new O2 sensor and see if my MPG's go back up... Thank you all for your help!  __________________ 2LT Rodriguez CA ARNG
