Accufab 70mm TB/intake plenum/intake spacer installed, question.

Man it was quite a bitch to get this one wierd sized bolt undone that was holding on the EGR valve. It was an odd size. Turns out it was metric (10mm). 7/16ths and 3/8ths would not fit but 10mm would, odd. I had to go to Sears twice to get the right sized socket. It ended up taking about 4 hrs total to install, LOL. The intake spacer raised it up enough that getting the EGR valve (that little black circular thing on the far right side of the TB when looking at the car head on) wouldn't line up right because it needed to be raised a bit. I had to get my dad to use a fuggin' broom as a lever to raise it up enough so that I could get the thread started. If it wasn't for that one stubborn bolt I could've had it done in 30 mins or so.

The gains are very noticeable. Definetly pulls harder throughout the RPM range. Feels like I gained quite a bit of torque along with the HP.

My question:

Now it idles real funny, it seems to idle at 1100 rpm and when I'm slowing down from a roll in gear, like coming to a stop and I put the clutch in, the RPMs rise up to 1500-1800 rpm or so and sit there for 5-8 secs, then slowly come back down to 1100. It's odd. I don't even need to give it any gas to start out anymore. It seems like maybe the throttle position sensor got bumped or something. Maybe it will go away in time. I did reset the computer by the way. Anyone else have this problem? And did anyone have that odd sized wierd looking bolt on the EGR valve on their '01? Thanks in advance.

i thought that the accufab and C & L plenums already had intake spacers built in to them :scratch:
yeah
i still have mine on because i can't find the stock bolts... :(
anyone know the part # or threading/length of the stock bolts? :rlaugh:

I don't have that idling problem but I have a 99... different plenums
 
Accufab 70mm TB/intake plenum/intake spacer

I've got the same setup on my 03 GT. Check your old TB and see if it has a IDLE SCREW you can adjust. On the newer models like mine there is no idle screw just a plug that Ford put in. I had the same exact problem untill I found out Accufab TB came with an idle screw, I had to close the screw in all the way and adjust the TPS. Adjusing the TPS is very important with a meter. Check the forum for lots of posts on how to make the adjustment. If you have an idle screw on the TB then you have a different issue. Hope this helps.
 
Thanks for the replies. I took out the spacer and now everything seems fine. Man I feel like a dumbass ricer, kind of like that kid who drilled into his cam cover on his S2000 to install his nitrous. LOL I was wondering the whole time I was putting that spacer in if it already had one because it sure did look like it. Oh well.
