New FD owner - high idle, backfire!!!!!
I just picked up a 1993 fd and am still quite new to the scene.

The owner who i had baught it off of did not do any of these mods, he had owned it for 3 years. The owner before him had done most of the work at a pretty well known rotary shop.
My question now is, since i picked up this FD iv been having some issues with idle. it sits around 1700 RPM and doesnt go down. Could this be because of a vacuum leak? I took it in to the shop today and the mechanic told me it MIGhT be because the seller turned up the idle to hide the irratic idle of a blown engine seal or low compression.. however the car seems to run fine in my opinion...
Also it tends to backfire quite a bit during low RPMs while in 3rd gear. the ATF ratio shows 14:7.. but after driving it, hits around 17: - 18: .. Could this mean it is running too rich or lean? Should i be worried about detonation?
I do have a apexi commander in the car aswell.. Im crossing my fingers that it isnt a blown engine or low compression im still waiting to hear back from the mechanic.
Could you guys possibily help shed some light?
Thanks in advance
