Alright! IIRC i have aboute 10-10.5 now at idle

I Will try! Thanks I have found an instruction and also a video Youtube. I know that is has to get the same position, thank you! To verify it is at the right place i can look at the fuelrate i guess? I have gmtdscan

Yes! OS is correct

Yesterday i tried to unplugg the OP sensor and drove 10 miles, and guess what NO fishbites! So what conclusion do we take of that? Dirty/faulty sensor? Or does this just cover for another fault because the truck is in "limp mode"?

The ones that are jumping around should do that, its fel related parameters. The only one who should not change with throttle is the tranny temp

No missed counts, i Will check the TCC

The scanner doesn't show anything strange, closuretime stays at 1,82 ms. And fuel mm2 too. Thanks for that but as I wrote in The first post the OS filter is removed

Only clean dieselfuel. And this has been going on for aboute a year and have tried diesel from other stations too. The sensors are working. The pressure is at uphill, highway its around 8-9psi

Hi! I have a 95 6.5td with 7500miles and have a fishbite problem. Moster happen at highway speeds, but i have 3 Times hard a exhaust poof while ideling. Things changed/deleted New Relocated pmd w. Extension. Also new harness from pump. Op filter removed New batteriets New ignition switch...

And a little video. Havent got any help yet with the harness check.

I havent either seen lockup in 3rd before, but i have not towed any thing yet. I did check the plug yesterday, no oil what i could see.. I Will take a closer look on the harness when i can get a helping hand from someone :)

Thank for the advice! wiggle the wires i Will try that. I havent thrown any parts yet, just my time and labor haha :) i have changed the ignition switch beacuse when i put in a new starter, it did just click, i turned the key multiple times when i did so i fried the barrel inside the switch...

Bought gmtdscan and took a test drive. The trans temp was around 70c(158f) and then for s millisec jumped up to around 149c(298f).seems to me that i have found a problem. But how will i now what to change? Internal harness with the temp sensor? I think it maybe be some kind of intermittent short...

And o also get a better video Normaly the Tcc locks at 4th gear but today i noticed it did it in 3rd, Will it lock in 3rd to if the ecm think oil is to hot?

Today it set dtc 58, wich is Transmission Fluid Temperature Sensor Low (High Temp). How do i diagnose this? Maybe measure with a pyrometer? What temp should it be?

I Will try to get my hands on a scanner I have heard that if fuelpressure is positive the ds4 Will make it pretty good, vacuum is not good. Yes i also think that is to low speed for the lockup to have something to do with it. It usaly lock at 80km/h(50mph) on 275/55r20. Maybe your right with...

Fuel pressure is 7-8psi at idle and 1.4psi at WOT, no flutter when the miss occurs. clear tube did not show any bubbles. What i can remember its just 3rd or 4th gear, but its very intermittent i can drive home from town 20-30 miles and nothing happen, but next time i drive To town it bucks...

I have Checked for air, good fuelpressure before the ip and LP relay mod. I have gone true all grounds i can find. Soon i drive this truck into a lakeo_O Sorry, now its done:rolleyes:

I can also mention that i have had missfire problem for aboute a year. Sometime i can hear a exhaust poof while ideling, and a quick buck in highway speeds

I have no codes, it does not feel like its slipping, more like a fast up/down shift. and this is just happening at a light throttle, if i give it more gas it shifts fine
