3.8 or 3.4

[bstuby]

I know winter is coming up shortly and I have been puttin mods on the car to run a 3.4 setup. I just installed headers over the weekened along with 180 tstat al 104 plugs and my cai has been on for awhile now. I just got my intense pcm in today along with pully puller. I been reading that during winter kr is a real b####. So my question is would it advisable to put my pully on or just run my 3.8 till spring

just run the 3.8 till spring

[gtpinsc]

any way to scan for KR?

[bstuby]

Would it run decent with my intense pcm on a stock pulley. I have my stock pcm in right now with no egr and no rear o2 sensor and its runnin like s###

Year of car?

[bstuby]

98 and I got a aeroforce on the way next week

[gtpinsc]

id put in pulley and pcm after aeroforce gets installed and see what ur workin with. hard to say why ur runnin like ****.. IIRC 98's should be ok with no rear o2.

[bstuby]

I will just buy a 3.8 pulley for my mps incase things go bad, but would any of you guys recomend runnin a 3.8 on a tuned pcm. Would it mess anything up? I ask because I have to send my core back so I won't have my stock one any more

[gtpinsc]

wont hurt anything... just wont run to full potential..

[bstuby]

Thanks a lot guys you been a lot of help

No egr or rear 02 wont make it run like crap.

[bstuby]

would the front o2 sensor cause a bad misfire if its not workin?

[blueguy]

It'll make it either dump fuel or run lean as hell time to time...so it could be causing a misfire...do you have any SES lights?

[bstuby]

yea i did have a ses light on. figured out what it was tho, #5 injector wire came unplugged somehow. still cant figure that one out
