Well, you had the distributor out, so have you checked the the fuel sync?

 

ok just bought thoes injectors, thanks man.

 

Just got my 53mm tb today!

Will put it on tonight if I get a chance. Still have to work out my idle/lowend problem. I think a lot has to do with the iac positioning/signals its recieving.

 

So I am working out the issue I have been having with my truck. It wants to have a real iratic idle loaping up and down from 300-600 rpm when you let off the gas and coast, that or it dies. Also it runs rough under 2200 rpm.

New

IAC,TPS,Pcv.
No engine vacume leaks vacume is fine. Fuel pressure is fine, and all injectors are fireing fine. Fuel sync-distributor has been moved around and the problem still exsits just to a varying degree.)

The only things left to check are -

map sensor( my voltage checkd out ok and the snapon scanner did not pick up on anything-doesnt mean the vacume part of the sensor is bad tho)
engine coolant temp senosor
intake air sensor

So I will buy these as soon as I can and see what happens.

I am told my IAC count should be around 40-60 but I have no way of checking that unless I go back to the shop and hopefully there snapon scanner/computer can read this. And if its off then what buy a new one again and hope its right?

 

Ever finish this?

 

Just a little helpful hint here..... On an old thread, you can check User Profile and see when the last time they were online. If it has been a while, I ouwld send a PM (hoping he has it set up to send an e-mail about the PM) and see if I could get a response from user.

BUT - good on you for searching for the 408 stroker! I actually would like to do a stroker after I finish the other project cars I have waiting on me!

 

Thanks for the tip! Yeah I'm now planning on a 410 stroker

 

Oh, go for BROKE! 426!!
