Timing Question??

[TheSlowLX]

When I advance my car around 15* - 18* and I come to a stop light or stop, the car begins to surge. Usually at a Stop the car idles around 650 -700 RPMS, steadily. But when I advance the timing, it starts jumping around like 500 to 800 RPMS, and since im on the brakes, it feels like the car wants to move forward, then suddenly it just turns off. Dont get me wrong, when I advance the timing and I floor the car, it feels very strong but the only thing that pisses me off is the part when it turns off at a Stop. Anyone else ever get the same problem? I do have an E-cam with 1.7 RR's, and I always use 93 octane on my car. Anyone have any idea what causes this, or is this just normal? Thanks.

Try backing the timing off to around 14.....15-18 is a lot.

When you advance the timing you must also check and properly adjust your tps voltage and idle rpm. good luck!!

you will need a multimeter to adjust your tps and you will have to adjust your throttle set screw to get the idol you were at before you adjusted the timing.

Hmm, not sure I understand the reasoning behind needing to reset the idle after adjusting timing. Please explain further. (I am not being a smarty - I cant think of the reason, but I very easily could be missing something).
