[R'enatoS13]

ok so here is the down low on the SR, RUNS LIKE SHIT!!! so the timing is off??? when i boost up to 7psi(pounds/lbs) it like boogs like a damn geo metro, i dont like it.. it used to be alot faster than it is right now... ryan "timed it" and its not the same anymore...i want to get it fixed please helped. i will be putting it down for the weekend. alot the bbq is going on but if anyone can help i would appreciated it. maybe the cams are off by a tooth? IDK.
Sam Funtanilla says its running on 3 cylinders?
its miss fires.
the spark plugs look like its running hella lean?

HELP!!!!

3 cylinders, or HORRIBLY lean/ rich. like misfires so bad i heard it from inside my house when he was idling outside.

i still think you have a vacuum leak.. only pullin 10hg's at idle. retarted ignition timing can also cause low vacuum. so one of them..

And having a dead knock sensor can cause ignition retardation.

true. i was tryin to remember how to read codes, but renato had to go home and feed the ducks or somethin

The thing has cam timing off, I swear. It won't run on 15° timing. I've set it a half dozen times. Mine purrs now and is set identically. Same timing gun, same timing method, etc. I set mine to 15° BTDC at 800 RPM. His won't hold a steady idle below 1200. So if it's off, I'm clueless and very sorry.

Maybe its something stupid like the injector harness on backwards, or spark plug wires on wrong, maybe the maf is bad or not grounded right....you guys double checked everything?

It was running just fine. Until we timed it again. I'm gonna do an oil change n put new spark plugs n clean the MAF and see if it fixes it.

if you think the cam timing is off pull the valve cover and check it, should be i 20pins between the two dowel pins on the cams, this is something you can do on your own renato, if it is off then maybe have someone come change it, cam timing is a very simple process, if the cam timing is off i can give you a quick run down on how to do and do it simply, but usually if you cant get the ignition timing correct then the cam timing is off, the CAS should be pretty close to the middle for 15degree

if it is not in the middle for 15 degree then you either have the cam timing off or maybe the head and block have been milled and you may need cam gears

probably a coil pack

bag in piping?
