Hi its me again, havent been on here for a wile cuse have limited computer time but i fixed my miss it ended up being the power steering pump belt to tight but anywho i got another problem when ever i shut my truck off it Diesels for like a secend then is hard to start up, I have done a tune up on the plugs, whires and dist. and timing it set at 8 on idle, only time it dosent do it is when i shut it off in drive but in park it sputter.. or w/e u would call it but anyhelp would be appreciated.

it could possibly be a air problem. i know that sometimes if the fuel/ air mixture is off my sons carb used to load up on fuel but not enough air to burn it all.

do you still have the t.b.i. or did you convert to a carb?

its a Holley 4bbl DP carb. I tryed cleaning the air filter with the K&N recharge kit, got the filter clean and looking new but it still dose it. this is my first carb. so not to keen on them could it be running to lean or maybe to much fuel its running of the Holley "Blue pump" outta a 10gal fuel cell but dont think thats the prob. cuse fuel pressure is at like 5 on idle maybe a carb. rebuild?

Throttle plates are open enough to allow air/fuel mixture to enter the engine as it "winds" down.
A hot (operating temp) engine will self ignite the mixture. Air/fuel contamination takes place during this time in the plenum of the manifold to you have to crank it a bit longer on the restart.
If possible, adjust the idle down as to get the plate opening a bit smaller. If the cam doesn't allow a lower idle, an idle solenoid should be installed for base idle and close the plates when ignition is turned off.

Would 200 digrees be to hot? it runs 200 all the time unless i stop at a stoplight then it starts to get hotter untill i take off again then it drops back to 200. but ill adjust the throttle plates and see if that dose anygood but thanks for all u guys help

no problem.

Just shut it off in drive, then shift to park. The added drag from the torque converter will kill it every time.

200 ain't hot, not with the crappy gas they sell us today. 230 is a tad warm, 240 is hot. Anything higher is the begiinning of a meltdown.

Mine runs 200 most of the time and might climb to 220 sitting in dead traffic in 100 degrees summer heat.
