    Hi everyone! I recently just bought a 99 civic hatch from a kid who swapped a y8 in from a 2000 civic ex. When I fired the car up after it sitting for a few days, the car had the common d series surging idle (1000-1500), but it would only do this when you just slightly touch the gas. After it...

    Hey gang, I drained my tranny to swap out my shift shaft seal (which didn’t end up fitting thanks to Timken), and I had to refill through the reverse switch as my fill bolt would not come off at all. I removed the battery in order to reach the reverse switch as well. Upon reconnecting battery...

    Hi, there! I'm sorry to create another thread about idle problems, but you guys seem very knowledgeable and friendly. I have a stock 1998 Civic DX (D16Y7) with the manual transmission. It has 192k miles on it. When I got the car, the idle would go up and down after it started to get warmed up...

    I have an issue with the idle on my d15B1. I have read all the items related to the "hunting idle" with Honda. I thoroughly cleaned the IAC, checked vacuum leaks and so on. The problem lies in that after startup and the engine gets up to temp everything is fine. Once I hit the accelerator...

    So I put together my turbo d16y7 recently; - 00 d16y8 intake manifold with the back iacv port and the injector air hole things are plugged and not leaking - stock d16y7 throttle body with the 3 wire IACV - chipped p28 ECU So the car starts up quickly, idles at 1500RPM for a bit and then goes...

    so i own a boosted D16z6 and recently my clutch line blew so i had to replace the hole system in order to finally get pressure to my clutch. Anyway, ive noticed that ever since i put all my couplers and piping back on (i had to take them off in order to have access to the clutch lines) my car...

    I've dealt with this surging idle ever since I did a head swap which leads me to believe that there is air in the coolant system. no codes at all Here is Everything that I've done: 1. I ran the car with the coolant cap off [jacked up the front end] and mashed the gas at about 2000 while the...

    Hey D-Series.org! I am new to these forums. I know there are thousands of threads about Idle problems but I think I have a somewhat unique problem on my hands. I want to try to figure it out with you guys first before I take it to a mechanic. So my car is all stock. Auto d16y8. On cold start...
  10. Naturally Aspirated
    Hey guys! I'm new here so if I do anything wrong (like post in the wrong section) just let me know and I'll fix it. Anyway, I have somewhat of a Frankenstein build. Its a D16Z6 with D16A1 pistons, tuned on e85 with other supporting mods. It's actually someone else's build that I bought and have...

    My Integra (2000 auto LS 180,000 miles) is acting funny. It runs and drives fine, but on cold starts, it idles really rough for the first 15 seconds or so, like it is only firing on three cylinders, then it cleans up and idles smooth. I have been cleaning and replacing parts/sensors one by one...
  12. Engine Management
    I noticed on my civic that I have the 3-wire IACV on the bottom of my throttle body, then I have an FITV in my thermostat running from the intake into where the fuel injectors are on the IM. A long time ago the nipples on the FITV broke off, and since then I have blocked where the FITV once was...

    I have a D16Z6 in a 93 del sol with a p28 ecu, Before i got my connectors sorted out there were like 3 different 2 pin connectors on the back of the IM weren't in the right component. I got the IACV connected and now the idle is too high. When i start it up cold its around 1000rpm and it goes to...

    i cleaned my IACV over the weekend because of a rough idle, now when the car warms up the idle surges/bounces between 1000-2000rpm. i didn't have this problem before cleaning the IACV and i'm 100% certain that i put things back the way they were taken out. i've since then i've retraced my steps...
