i was having problems with my fuel pressure and maf codes and now that is fixed. what is happeneing is with or without the chip. it has a rough idle and when i acclerate slowly it seems like the engine is working too hard and feels very rough. this happens only up to about 1500 rpms and then everything seems to smooth out. doesnt matter hwat gear or how fast but when im slow with acceleration and the rpms are low is when the problem occurs. the only other thing i noticed engine wise is that my tensioners seem to be moving with the rough idle, ive never noticed them to move before. its mostly on the sc pulley and one real low on the passenger side. do i need new tensioner springs and is this causing the rough idle? spark plugs and wires are new, fuel pressure is at 43 at idle, new computer and new maf. i have no codes and no cel. mods are on my member page.
