I have a problem that no one can seem to figure out!!

[daveismissing]

Are those bare wires running thru the firewall without a grommet or sleeve?
Do yourself a favour and fix that first.

[Just a Six?]

Not sure what I am looking at there, but someone rigged the wiring...eithe r because they thought it was something trick or because something was broken.

That green wire round plug looks like #27 the Coolant temp Sensor??

I don't have to buy the coil and module ..... have a lifetime warranty for those .... so that plug plugs into the block ?

goes to the high speed fan switch sensor

Other then the radio sounds good, Scanmaster didn't show us nothing and you didn't video the engine.
Maybe you can try again, but this time run the video a bit longer to engine at idle and higher rpm, and also show all Scanmaster numbers.

Ok i got a new module the coil tested good . Now im gonna get another ecm cause im not sure if my has a problem . Can anyone tell me what a cal pak is and what it does. I see it as a option for a new ecm.

[Steve Wood]

It's the smaller chip under the normal chip in the ecm.  Just pull it out of the old ecm and put it in the new ecm.  It has the limp home stuff in it and does not normally affect how the car drives

Ohh Snap!!, i got another problem i was changing my air filter put it back together now it runs like crap! I unplugged maf it ran better at idle until i press the gas. No check engine light or codes even when the maf is unplugged. I thought i would get a light or code when the maf is unplugged. Seems like maf took a dump, whats your take on the new issue? Seem like before i can fix one problem another shows its ugly face.......I'm frustrated!!!

[we4turbobuick]

Ohh yeah the O2`s are staying at 000 .....?

[Steve Wood]

what is your fuel pressure at this moment?

What maf numbers is the SM showing at idle now?

[we4turbobuick]

The fuel pressure is the same ..... ill check the maf reading as soon as i get home....does this sound like a bad maf to you?

[Steve Wood]

late model mafs don't fail very often....so I don't know.    000 o2s usually mean low fuel pressure or a very high maf reading.   

Check your blms as well.

What chip did you say you had in the car?

[we4turbobuick]

Turbo tweak

[we4turbobuick]

Ok ... i just got home the fuel pressure is around 35 psi the AF is 04 the blm`s are 128 ..... the maf sensor was used ......
