Help!! CEL Flashing, Engine Shaking when i turn on A/C
i have a 99 civic lx that i got a month ago. bone stock, it doesn't look like the engine bay's ever been cleaned... so i cleaned it. i've cleaned a lot of my previous cars' engines and never had this problem.
i used:

now the car runs just fine until i turn on the A/C. then the engine starts shaking like it's about to stall out (it doesn't) and the CEL starts flashing. I turn off the A/C, let it sit or rev it a few times, and it evens out and the CEL goes away. AC still works.
as far as i can tell, all other electronics and mechanics of the car are still working.
any ideas?

ok now it's even worse.
it's really hard to start up the car and when i do get it started, it idles fine
but if i get on the gas at all, it "bubbles" and hiccups and dies. maybe a vaccuum leak or something?

im having the same exact problem with my 93 dx coupe! when i turn the a/c on the car shakes hard for a sec, evens out and i drive normal! and some times when i try to start the car it takes a lil over 5mins to start (me turning it on and off) and im trying to find out what the problem is (i know its like a big run-on sentence).
just to help a lil my compression is 195-190-200-195!
