Lurging at StopLights

[Elk_hunter]

Hi all,

This has happened a few times now, and Dont know if it's a good or bad thing. I'll be at a stop light with my foot on the brakes, and the explorer will jump/lurg . The brakes were change a few months ago.(was doing this before the brake change)...the master cy is working fine.
Does anyone have any info on this? Could this be a transmission thing?????? Thanks!!

Are you getting a check engine light at all?

 

[Alec]

Do the revs go up? Or does the truck just jump a bit?

 

[Elk_hunter]

check engine light is on. two codes I get are 133 (o2 sensor) and 433(egr valve).

No the rps do not go up. It did it again today, and I noticed when the electrical fan kicked it, that is when it happend. But later on the fan kicked in and nothing?

Does it do it early in the morining? Mine does something like that every morning (at the same stoplight I sit at for about 3 cycles). Mine feels like a choke is abruptly cutting off.

 

[Elk_hunter]

nope. It has done it right after its been started,,and also after 2 hr highway drive. the first light we came to . it did it?

I'm really stumped on this. Dont know if this is bad thing or just something weird that happends

I would clean my MAF and IAC along with the air filter... have you ever replaced the 02 sensors? If not I would go ahead and do that and see how that works. My $.02.

Mines done the same thing a few times...reminds me of sitting on ice with the brakes on and the rear trying to spin....Let me know what you find out.

Common for Me!

That same thing happens to my 95 XLT Auto. Just sitting at a light and it kind of surges forward. A few times I thought I had been bumped into.

It has proceeded to happen for about 5 months now and nothing seems to have come from it. I have even towed a big boat and done a bunch of 4X4 and it works fine. I am counting my blessings though.

I ran a thread and didn't get that much knowledge, I think it is a bit hard to explain.

I thought it may be my torque converter carching while not completely warmed up. It happens just every now and then, I think that I have become accustom to it.

GOod luck! If you find anything out please post it.

that happened in my Mountaineer recently. i had also thought i got hit, and i was ready to get out and hit the guy behind me for hitting me, yet there was no one behind me.

it also happened in a Whinabago i drove once.

Like I said in an earlier post, it always happens at the same light in the morning; one morning it happened twice. I looked in rearview, and a Honda was on my bumper! hehe

Same thing happens to me. When this happens do the rpm's fall and then rise back up?
