Hey guys, Im new to the forum and i hope i didnt post this topic in the wrong area.. SO i have a OBD1 complete Gsr Swap in my 93 Civic hatch..Long story short my car was bogging downwards/upwards for like a good long month. During that process i changed out everything i could think of that would relate to my bogging issue.. i changed out my spark plugs,ECU,fuel filter,fuel pump, MAP sensor,IACV, Distributer + relay. so after all that i my bogging still continued.. Finally one day i had a honda expert and he found my problem..Oil was in a plug that was directly under the distributer, he cleaned it out as well as changed a few plugs from my wiring harnest. My car was running awesome for like 2 weeks...then the day before yesterday i noticed the bogging once again. I checked the area that was infected with the oil and i couldnt find anything..so seems like im back to square one again..Can anyone please help me out? I really dont know what else is missing and its bogging like crazy again..plus i have NO check engine light...any info is GREATLY appreciated!
