Draken273

she runs fine when cold, doesnt wanna start when hot
Unplug the MAF/IAT and she starts but runs rough.

brownish/white smoke out the right bank
clear exhaust out the left
(theres no h or X pipe and no airpump)

Once she gets running again you can usually plug the MAF back in and shes fine.

any ideas?

Last time i checked she had codes for running lean one both banks, but she sounds/behaves like shes rich.

1995 5.0 w/ slushbox if it helps.

You need to check for codes again, it's so simple a caveman could do it. Write them down...KOER http://oldfuelinjection.com/?p=94 KOEO http://oldfuelinjection.com/?p=13 By the way, a bad TFI module will cause it to not crank when hot and so will a weak battery.

Pull the maf sensor out and clean it with carb cleaner, just spray it real good and put it back together. Your TPS voltage needs checking also, here's a link on how to do it...https://mustangforums.com/m_969165/tm.htm

Ok, she cranks, No fuel it seems like, she cranks stumbles and dies. when i unplug the MAF she'll crank then you have to hold her at WOT for about 15-30 seconds, she will climb to like 2K maybe 3K and then start acting normal. Ill go out and get codes soon

Pull the IAT and clean it with carb cleaner and an old toothbrush. Does it surge when it starts?

She'll crank, then sputter then die witht he Maf/IAT plugged in

unplug them and she'll crank, sputter but if you hold it it to the floor or atleast half throttle she'll slowly bring her rev's up. but she'll die if you let off the gas.

just ran the codes, KOEO only, she wont stay running for KOER, and already cross referenced the codes, had codes

172,176 L,R banks lean cond,
332 EGR Insufficient flow
334 EGR closed voltage high.
157 Low voltage at MAF(it was unplugged prior to reading codes)
158 High voltage at MAF
and i dont remember the code but it was low and high voltage at the IAT but again, it was unplugged

Clean the MAF and Iac.
