im actually trying to figure out the same prob on my ls motor and ive swapped alot of stuff (dizzy, plugs, wires, etc. injectors, fooled with valve adj, timing) still havent found problem so if you get yours taken care of let me know

 

I have the same problem pretty much, most likely I'm going to go to the dealer, seeing as they have better diagnostic tools than I do.

me too post how to fix it.

 

ok i fixed it yesterday....

i guess from using shitty plugs, it blew them to a .065 gap...so i replaced them with NGK 7series a few days ago and the hesitation was still there, so i was like what the ****, come to find out, as i pulled one of the wires off to check the plug, i noticed that i didnt have one of the wires pushed all the way in so it wasnt getting all of the spark haha...its all fixed now

that sucks... i know that isn't my problem... thanks for nothing. j/k...but seriously i don't know what the hell could be wrong with mine?

 

what are yer plugs gapped at?

 

to be honest i'm not sure. my car is running rich i think. my problem is that in between 1k and 3k rpms, it bogs down really bad. above 3k rpms it runs fine. tried different dizzys, map sensors, injectors, tps, fpr...ect. nothing has worked.

 

had the same problem and it was cuz of the gap in my plugs, you should check them, im sure that could be it....it was for me at least

 

well i figured it out. my intake mani gasket was leaking. replaced and now it runs fine.

 

nice how did you come across finding that as to be yer problem

 

after switching everything else that is removable... i figured that was the only thing left.

You didn't even check it? Just replaced it, huh?

well....i lied. it worked for a little but once the engine got warm it started doing it again. WTF? does anybody know of a good website that deatails where the cavume lines go? it has got to be a vacume leak. the plugs are white showing a lean condition that can be caused by vacumelines.

 

Dude,

Check your spark plugs and the gaps. Replace with new plugs and set gaps. Your stumble is caused by the misfire in the gap of the plug. I just did this in my Teg. If that is not it, which I'm sure it is, replace the spark plug wires. Keep working your way back to the distributor...though, I think a simple change of the plugs will cure the stumble.

Your problem is strickly ignition since your not smelling gas.

 

spark plugs are brand new. wires have about 3000 on them. i'm going to try new cap and rotor today.

Didn't you do that already? Did you check them?

 

it doesnt matter how new they are if they arent gapped right

brand new pre gapped. still not working right. the plugs are white... as in running lean. but the fuel pressur is dead on. i'm missing a vacume line or something.

 

what was the pre-gap?

 

same as spec. don't rem,ember exactally... but it was the same thing. I'm taking it to the local performance shop today so i'll let yall know.

 

werd, cuz i used pre-gapped ones and it wasnt correct

 

faulty/clogged injectors, bad O2, clogged EGR, faulty TPS, faulty EACV.
