could a tps thats a little off (acts fine except a quick stop and the engine stays at 1000rpms and you have to tap thegas pedal to idle it down.) and the ignition being retarded like 2 degrees cause my car to pulsate on acceleration...more noticable in od...from like 1100 to 1500rpm only. if not what in the engine bay could cause this. (all vacuum lines connected, no apparent vacuum leaks, and did ignition 3 months ago.plugs are a little oily from valve seal leak but i fixed the leak and put the same plugs back..they should of cleaned up by know though right.) i noticed this after i did my v seals 2 weeks ago. im at 1/4 past zero lash by the way.
