[89purple horse]

the purple horse is a 89 with a efi 351. when its cold it fires up just fine and ready to run. runs pretty good untill it warms up then it seems slugish i dont get no check engine light or anything. could that be egr? gas inlet tube off manifold broke during header swap and have not been able to replace it yet. the other thing is its hard to start when its hot it acts if the battery is weak but its only a month or 2 old. i am leaning towards its in timing some where but i am new at the tfi system can so one help someone help out a lost shade tree mechanic

Welcome to da ZONE!
Have charging & starting sys tested for Free at a local parts store.

I'd do a Self Test for Diagnostic Trouble Codes (DTCs)anyway, such as this by our good friend, BroncoJoe http://broncozone.co...587&#entry74587

I run it around to heat the engine up and shift thru all gears incl Reverse.
then; turn off all accesories/lights, etc.

Do KOEO portion first
For Key On Engine Running (KOER) portion, the engine has to be @ normal operating temp.

Posat any codes found here or look em up in my broncolinks.com site.

your SPOUT connector is @ Distr; such as here;

Of course there are more that could be tested; do that stuff first

thank you very much for your time miesk u were right i pulled the spout connector and re timed it and it ran like a champ for a couple days. and now i think i am having starter issues cause now if i go on long drives and shut it off it will barly turn it over (but runs awesome). i have read in some threads that maybe the headers r causing the starter to get to hot. can some one verify that for me ??

Yes, that's quite possible that the headers are overheating the starter. You can try putting a heat shield over the starter, or wrapping the headers. JSM84

ok thanks for the info. i am out of work right now and times r kinda tight and the header wrap is pretty spendy but a buddy has some extra that would probly cover the starter think that would work?

[miesk5]

yo!
Thanks for coming back to update!

Yes, you can use that wrap as well as anythAng else you can scrounge up around the house incl pieces of appliance case steel or ss; look at the cat converter's heat shield; same principle.

One other thing to check is your ground cables. Mine had corrosion inside the cable from years of being on and as it got warmer it got harder to start. A new ground cable stopped it from a sluggish restart when it was hot.
