hard pipe's and big intercooler $400.00 plus shipping thanks dran1

So my volt meter in the dash usually reads around 12v. This scared me at first until a I took a volt meter and tested voltage at the battery and got around 13.5-14v. Figured the gauge was off. Ran this for a while now. Recently my blinkers stopped flashing. They would blink for a few seconds, then just stay on, hazards worked fine. replaced the flasher w/ an EL-12 unit yesterday. Tested and they seem seem to work fine. Went back out about 2 hours later to replace my wipers. Went to test

Well I finally got the quest running, she is running good..however she has a high idel(1300 to 1500 rpms ) and sometimes the idel will surge up and down 1500 to 1000, I have set the TPS and the ISC twice but I can't get it corrected, I have tried adjusting the idel screw and what I mentioned before...any ideas, thanks for the help.

Can find them for like 3k running ready to go. Anyone Think im crazy? Look into them if you dont know what they are. Google search deuce and a half. Seems like would be a blast.
