hmm, i see nothing in my cluster about this light or a seperate switch in the dash. i see motronic has basic codes you can check with jumper and led with harness under shift boot. i will check my car tomorrow for that and see what happens.
i tightened the distributor bolts and no go, timing light still jumps around. i tried various spots on the spark plug wire no change. i tried hooking up the timing light to the - post on coil to start like the bently talks about, this would illimunate light on my gun but it wouldn't flash, so i used the instructions for my gun and put it on the negative battery post? i'm not sure what to do here. i hate to spend all that $$$ on a new one for no reason. i got antsy and took the car out for a hard drive and it was definately a different experience than before. not sure if im crazy or if the cams, chip and intake could have made such a difference? now i have a cat on it and the car is much quiter walking around it at idle. the engine bay specifically, and so much so when driving i thought the car died multiple times when coming to a stop. to my ear i feel there is less crackling out the exhaust pipe, but it seems to me i hear and feel a new drone right under me when just coming off idle. i would have called it a hesitation and gurgle but i noticed it isn't directly related to the throttle when pusing it to go. on that front the car seems to react as good as ever without stumbling on the gas. that drone seems to go away when revving it out, and will come back at times when letting off the throttle. the car was always too loud for my liking when driving it but i don't really care at this point, i will get rid of it later anyway. i only drove for like 20 minutes and when i came back the car stunk. not like raw gas smell, i wonder if its the cat breaking in? of course they mention nothing about it. i am hoping i am on the home stretch here. i am tempted to just take it into smog but i have to assume my timing isn't perfect and am afraid of failing and having to go back :( only issue i noticed again is i turned the car off and it restarted right away. when i went out for the drive, maybe an hour after previously running the car had no life starting the first crank. second crank it sounded like it stumbled at the end. third crank it started and idled on its own. so is it safe to assume i have a problem with "cold" starting? it didn't use to act like this, it always showed signs of life.
