speed density? i really don't know what all that is you would have to explain to me...basically the car runs like it did when i accidently left the maf sensor unplugged...however, i'm POSITIVE it is plugged in now...also i don't know if i mentioned it before but car smokes like a champ now...and it runs like it's out of gas (which i know it isn't) ie bucking and loss of power then random power surges...

alright...i'm off work now...the car runs EXACTLY the same with or without the maf sensor plugged in...so i'm guess that i have a faulty maf? where can i get a cheap one that works...oem or aftermarket...or is there a way around getting a new one...

I posted this on the previous page but you might have over looked it.
About your reverse. Pull the ENG SEN fuse from under the hood and check it. If it's blown then there's your problem. If you don't have another fuse just use your horn fuse as a temp.

you can switch the rear o2's with the front and see if that helps since you dont need the rear ones anyway (rear o2's basically just tell you when cats go bad), but i dont think it will help since you said the car just cut off when you were driving. if the o2's were messed up that bad i would think it would jack up normal driving as well.
as for the comment about unplugging the maf and trying sd... i dont think that will work either. its not that simple.
as far as the reverse lockout... can you muscle it into reverse? mine wont let me over sometimes and ill need to use two hands to get it into R. if you checked the fuse under the hood and it was good, then get under the car and look at the solenoid on the side of the tranny. im not sure exactly which side its on, but on one side is the cags (IIRC) and on the other side of the tranny is the rev lockout.

yeah i was showing codes for both revers lock-out and skip shift...and that was after i went plowing through the dirt on accident...so maybe it pulled the connectors out...i already switched the o2's and that did not work...it doesn't matter anyhow now...the car is at revxtreme and they said the spark plugs were toast since its been run so rich for so long...i hope to be getting it back today
The car is blowing the main sensor fuses... now we have to figure out why. Last time I saw this happening, it was due to a pinched wiring harness, between the block and transmission. So we're going to be tracing every inch of the wiring harness looking for a burnt, stripped, or pinched harness wire.

that's odd...you have a pm with a few more details of the car...also i did remove the amp a couple days ago...but i don't see why that would affect the way it drove...just trying to give you whatever i can think of so you can get it up and running...
Think we have it fixed... whoever put your car together didn't pay attention to details when running wires. 
I should know by later today, if we have that problem fixed, with the blowing the main sensors fuse. If that's fixed, we'll tune it, and you'll have it back within the next day or two.

thanks dino...i'll be there around 10 tomorrow to pick it up...i guess the power was so-so...i didn't really know what to expect since i didn't know how well the heads were ported...all i noticed is that the intake ports were smoothed up a little when i took the intake off...i guess it's not bad for cam only but for heads/cam it's not all that great...it's all good though...as long as it drives well and stuff...i'll prolly be stepping it up in a year or two anyhow

WTF!!!
Kevin, what happened man? How bad did you hit the dirt on your accident? MAF never showed any problems when I had her.
Dino at RevX:
The car was mine up until about a month ago. I'm responsible for the work. What exactly was wrong with the wiring? Can you be specific?
Btw, what were the numbers after tune?

The wire protecting loom didn't get put back on, and there are two brackets on the back of the engine that are metal, that hold the wiring harness securely, and they rubbed through the outer layer of the wires, and shorted them out. That's why it kept blowing the main fuse for the sensors, and that's why the MAF wasn't reading.
Car runs great now... cold start up, hot start up, doesn't matter. Now you have to think about getting a clutch and maybe some tranny work. It doesn't like going into the gears too smoothly... especially 3rd. Nice car, just needs a little love.
