"lope" idle at start up with block heater

96 f250, 215k miles, stock other then 4 inch down pipe. Only had the truck since august.

The glow plugs/gpr will be done soon. Cold start in the mid 40s is possilbe, but turns over a lot, then get white smoke, and keeps smoking till she warms up.

Plugged in, she turns over fine, but "lopes," 2-10 times before revving up to a normal idle. A slow 1/4-1/2 second chug, chug, chug. Whole cab moves with it. I've experimented with cycling the plugs longer and shorter when plugged in. More cycling reduces the amount of "chugs,", but it was till there.

Any ideas? Is it even an issue?

Thank you,
-A

Re: "lope" idle at start up with block heater

Read something on here the other day that it can be related to a poppet valve on the top of the injectors it starts weeping oil around 200,000 to 250,000
The wifes 2000 does it sometimes when really cold 206,000 on the odometer
Do a search there is a write up from one of the injector gurus on the cause of this and what other symptoms can occur.

Good Luck

Re: "lope" idle at start up with block heater

Thanks guys. It is at the point where the injectors are questionable.

How ever, it only rumps when it is plugged in. No plug, no rump, just more smoke. Hmmm.

But you also said that it has a long crank time when it's not plugged in. Perhaps the long crank time allows something to build up pressure or purge air which reduces the lope?

I'll be watching this thread. My '95 loped hard for a few seconds on cold start........ back when it ran. Please post up any findings!

Re: "lope" idle at start up with block heater

is the block heater actually working? The coolant in the upper hose eventually gets warm after its plugged in. You still need a good GP system, but the block heater makes for every nice starts.

Pretty sure the block heater is working. After being plugged in, the temp guage is warm, motor starts right up with few turns over, and no smoke. Just a few rumps.
