I Swaped in another known good MAF and the car still has driveability problems and poor idle conditions??
The car bogs when I snap the throttle and is feeling like it's losing it's tune??
Then on very random nights the car will cut off when crusing and the check engine light will com on for about 10 sec of untill the car snaps out of it. WTF???

Any help would be great and thanks for reading all this

Tonight I'm gonna check every plug including the 10 pin's, dist, MAF ect so I hope to fing something.
Could o2's have anything to do W/ this problem??

You swapped the electronics off of the MAF onto yours or the whole MAF including electronics????

The whole MAF.
If the alternator is taking a shit will that have any effect on the car. I know ot's charging but it will not hold a load?

HELP!

OK I checked everything last night from 02's to ECT and any other sensor I could get my hands on.
I cleaned every single connection including the 10 pin's and they were clean anyway. All my plugs look real good;not a spec of corrosion on them.
I even added a ground strap into the circuit to make sure I have a good ground for the computer.

The car still runs like shit and wont hold an idle WTF I have checked everything I think and am clueless now

I'm gonna try swaping in another computer as well; is it possible that it has a problem like this???
Thanks for any help

Hey have you tried this yet? How did you check the O2's, I posted this in your last post....

"Have you tried starting the car with the O2 sensors disconnected yet. Disconnect the negative battery terminal for a couple of minutes. Then hook it back up and start the car with the O2's unplugged. This will allow the car to run with only the MAF and in open loop. If it runs then it's not the MAF. Did you clean the element yet? If it doesn't run still then hook up 1sicklx's MAF. Just a couple more suggestions for ya."

Also can you post or e-mail me all the engine mods you've done. What type of tune do you have on the computer. Did this all of the sudden start happening or did it start when you installed something. Just trying to help.

Ray

TEST

I forgot to try runing the car with no 02's pluged in. I now know the MAF is fine cause with either one pluged in the car still runs exactly the same.
If I run the car with no 02's will it tell me anything else like if an 02 is bad or something???

I thought that when you first fire the car up it does not take any readings from the 02's untill about a min.

hey hows it goin well we are haveing the same fucken issues with my friends freddys car

I posted to see any one had any ideas
today we are goin to try swapping parts from brothers cars

I'm thinking it cold be the idle air bypass valve
or the 02 sensors

we tried swapping TFI and well same shit the car will idles for a minute and die once its warmed up

it drives but it jerks at low rpm and once you get into high rpm its fine

I'll let you now what we find since since we have my bro's car to take parts off and try diffrent things

Ujstlost please do get back to me cause the problems you are describing are very similar to mine.
I swaped in a known good idle valve and same shit.
The idle valve would not cause boging when driving at low R's like you are explaining.

The only thing I have not swaped in yet is TFI and TPS, computer.
Well lemme know what you find out Bro

OK cool I still have not had time to dick with it any more but I hope the TFI is fucked or maybe computer.
I just wanna find it.
Is the car your working on have a blower??

If this is just an idle problem then I would try fords lil spacer kit for the bypass valve.
I didn't work on mine but they made it for same problems were having. [Fucked up design]
