with old TB the iacv was cleaned mamy times and rpm issue got stabble tempo but in past few days the rpm drop and rise was common and not getting fixed so finally he changed body now rpm is perfect no drop or rise but car is heavy even after changing fuel pump injectors filters multiple times. car ki piick halki nahi hoti agar hoti bhi hai to for few days then back to heavyness. car doesnt go too fast seems sluggish.
have the fuel filter checked! and besides that if ur car is auto check the condition of the auto tranny fluid and the filter! and ho sakta hai that the TB that he installed aus ka TPS kisi neh pehle seh chayrawa ho thats why u feel keh gadi bhari chal rahi hai! and there is even a possibility that the injectors that he installed are choked! get them ultrasonically cleaned and reverse flushed by having them installed on a proper machine,tested and cleaned because yeh injectors kachray kabarh mein parayway hote hein with time ain ke nozzle mein kachra phas jata hai and there is a possibility that aus ne ghalat cc keh injectors lagai hein!and agar fuel tank mein kachra hai woh saaf karwa keh fill it up with shell ka v power and see if u feel a difference
will try the injector cleaning but what if on scanner injector reading is 2.4 and i remember getting my old injectors cleaned and they worked like a charm for me for 5 days only that encouraged me to change them so i did that but no use. i will also try to clean the filter that was put in a year ago......on the scanner electrician says all values are good also engine load is 30

Hi,Do you have pictures of fuel pump assembly, i am not sure the one in my car is the correct one for civic 2003 exi prosmatic.
Hi, I am having the same issue with my civic 2005, rpm drop, did you find a permanent solution after all?
Nope. The post is 6 years old. However, you shuld get your car scanned for any codes/ errors thrown by the ECU. Will give you an idea.
