ok so recently i decided to retime my sr. i followed the FSM VERBATIM! removed valve cover, removed CAS, set motor to TDC( first mark on the left side of the crank pulley). the dark grey timing links were lined up. i dont even think that the chain has ever been removed since the motor was assembled. anywho...lined up the mating marks on the CAS and stabbed it in and it lined up. so i tightened it back down and tried to start the car.

ok. the car was kind of hard to start up at first, but when i managed to get it started it "loped" up and down.

hooked up my trusty dusty timing gun just to see what the timing was set at and at operating temp it was almost 20 degrees BTDC. so i shut off the car and unplugged the TPS and started her back up*****HERES MY REAL QUESTION*** How exactly can you tell when the car enters "timing Mode"?

is it supposed to exhibit some tell-tale sign thats says "hey im in timing mode"? i think this could be where i am going wrong but i timed it and got it as close to 15 BTDC as i could. its almost seems like the marks on the timing gun are rolling around.

after everything was installed i drove the car around and i noticed that its not really pulling a good vacuum at idle and there is a slight hesitation around Mid-Range RPM. new plugs, good gas, good fuel pressure. im clueless. if anyone has anything helpful please let me know!

does it seem to vary in power response? like sometimes its great and sometimes it feels like a moving fart

have you checked your maf sensor. that might have something to do with it.

I tried pulling each plug to the coil packs and injectors to see if it would effect the motor when i pulled the first one..nothing happend..so i was only running on 3 cylinders..it wasnt getting fuel...so i swapped a few things around and walla..NOW I HAVE NO SPARK IN ANY CYLINDERS??WTF...FRIED ECU MAYBE?
