Is your MAF plugged up?  FPR getting a good vac signal? Spark plug wires on correctly?

[shmed]

well I tried it with an without the maf   no difference
wires on correctly  checked twice
theres vac at the fpr 
any more ideas?

[Steve Wood]

is the tps reading properly on the scanmaster when you open the throttle?

[shmed]

yes goes up an down when peddle pushed

[shmed]

what are the o2s at idle warmed up?

If this is in Park, your iac's are way off but i would not think that is the current issue

Is the pcv line connected and is it in the intake?

What is lb above in your readings?

[shmed]

yes pcv still in stock location an hooked up
yes in park  put in drive can only idle   or will stall
lb im not sure what that stands for it comes in like that on the scanmaster.
can I just unplug the iac  tps  mass an try it that way??
any ideas
its a tt chip
worked fine before I fixed all the vac leaks an oil leaks grrrr
what did I  do now

[Steve Wood]

must be l8 for lv8

What are the O2s warm?

Do the maf numbers change when you try to increase the rpm ?  What do the O2s do when you ease down a bit on the throttle?

Don't see any need to disconnect anything.

Did you double check the wires-I have messed them up more times than I can count even tho I took care to get them right

[Steve Wood]

As coincidences always bite me in the butt, make sure the fuel pressure is where it should be

[shmed]

I triple checked the wires      idles too  good for them to be off
starts   great.
ill let ya know about the rest bit ofa storm here now

[shmed]

fuel press line off 42   line on 40

[Steve Wood]

guess i would start by trying to find out why there is such a small fp difference as it should be down in the thirties with the hose connected.  Sounds like you have a pretty good leak somewhere

What are the O2s, idling warm?

[earlbrown]

What do the MAF number do with KOEO while pushing the gas pedal?   Do they go up or stay static?

I was sorta thinking this too,  Did you take the intercooler off during these repairs?  I've had my intercooler hoses pop off and the car doesn't like it at all.  Listen to Steve and Earl...they know their shit...
