Within two days of installing these I'm getting the following codes P0503 and P0300, whats going on here and how can I reduce the vibes, I think thats whats triggering the codes

 

Same thing here. Just installed and tripping codes P0300 and another code, cant remember either excessive crankcase pressure or a lean code. I was told that these wouldnt increase the cabin vibration THAT MUCH, but if I have a pop can in the front cupholder it almost bounces itself onto my lap.lol. I really hope these things mabye "break in" or something because for a dd car I can stand this.

 

odd..these were supposed to be better then the ttr set lol, sounds like they are WAY worse

also, a p0300 code is a random misfire...

 

yea i know what the code is, im just trying to figure out how to get rid of it, otherwise im selling these mounts

 

i have had these mounts on for over 2 months with none of this. obviously the p0300 is random cylinder misfire and p0503 is a vehicle speed sensor. vibes will not trigger those codes

 

Mounts triggering misfire codes? riiiight

 

no, full poly is horrible. like you dont even understand. ott stage 2's are worlds better than any poly mounts

 

if you have really bad vibs loosen all you mount and shake you motor then tighten everything back up i barely have any vibs with stage 2 rotated mounts

 

x2 it only vibes with the AC on at idle. off idle its fine

 

I don't know how you got the 503. Mine have been in for months now and that hasn't shown up. I had the random misfire but that's due to the build and things needing fine tuning.

does anyone get vibes when crossing over 2k rpm? That's when vibes are most noticeable for me.

 

doesnt matter any more for me lol, cams and such made it vibe pretty bad anywho lol
i did find though that after installing lightwieght pullies that my vibes almost went away

 

during installation aren't you supposed to not fully tighten the mounts then drive your car for like 5 min to settle eveyrthing in and then fully tighten? did you do that?

 

I have JBP poly trans mounts and engine mount and have never threw a code

 

i was about to say lol, if poly is so bad then why havent i thrown i code either lol

 

im going to loosen them up tommorow and retighten them , but I dont think its a coincidence that these codes popped up the day after and the tune hasnt been changed for months , never had these codes before

 

If that's the case, my TTR mounts are up for trade Rodimus. What can we work out?

 

How mant times does it take for a cobalt owner to be told for him to understand a misfire code has **** to do with the mounts?







answer: we don't know yet 'cause he keeps on asking

 

dude seriously...mounts causing misfire and a VSS code? thats like saying i installed the mounts and got a flat tire the next day! mounts are not going to do anything like that

 

Know any good ecotec builders in orlando?

 

if you do loosen them up. loosen all four and shake it around a bit

 

Seriously... A mount causing a misfire?

come on.

 

apparently from reading other posts on here when i did a search im not the only one

 

hey, if youre sellin, im buying.

 

I still don't see how you can get a 503 from the change in mounts.

 

i haven't had any problems. just try loosening them all up and then retightening. but don't over tighten the main bolt that goes through the mount so much that the spacer rings and starting to compress
