I recently just cut my cat and muffler off they where in bad condition so i just took them off, but anyways after i did that my idle is very high when in park it will crank and instantly go to 2500rpm and then it will go back down to 1500 rpm and then it will start going up higher gradually...

So i just got my carburetor rebuilt, put it back in with new vacum lines, cleaned the fuel system, replaced fuel filters, new fuel lines, and cleaned air filter. Before doing all this my dad bought the car and it did not start at all it had a crank but the engine would not turn over. Now after...

Hi all, this my first post here, but I recently got a '91 3rd gen prelude that has some issues. It's been around me since about 2016 or so, so I know some of the work that's been done on it. For example, my brother took off the exhaust manifold and replaced it with headers. The problems started...

I found a 1998 prelude. Straight, clean, 5 speed, low miles. Everything works. But its having an idle issue, if you dont constantly give it gas it dies. So stop light, put the clutch in. But when your driving its an amazing ride. Seeing what kind of fix it would be and if its worth it 3500 for...

Hi, I have a 1992 Si with a 2.3 motor, all original with 80k miles. Last year, i installed an AEM cold air intake. after complete install, the car will idle, then surge to around 2000 rpm, and get hung up like that for 30 seconds or so...sometimes, a quick hit on the gas will spike the RPM...

Umm soo i think I’ve looked everywhere on the fucking internet to find a new throttle body seeing as my screw is striped and my throttle body its self is cracked, I bought one on eBay but it arrived today and I was disappointed to see that it was very dirty and very much stuck closed. Is it...

I have a '99 Base.. I have a few issues. I am hoping they aren't issues at all. I just got the rear main changed, clutch replaced, and the serpentine done.. In the past week, I went to vtec and then had a flashing CEL... but it went off after 10 seconds, took my OBDII and no codes were found...

Idle is surging between 1k and 1.6k. Cleaning the IAC valve didn't fix the problem. Blocking off the top port that goes to the IAC (inside the throttle body) makes the engine idle normally. The bottom FIT valve port (inside the throttle body) is sucking in air even when the engine is warm, and...

Hello everyone. I just picked up a 2000 a few days ago, and noticed a problem while driving it. I did a pretty good amount of searching before posting, but I could not find results that matched my problem. When I start the car and start driving, the car runs and drives fine for about 10 minutes...

Here's my situation. For a while I had the fluctuating idle problem but it went away on its own. More recently I started having a low idle problem where it nearly stalls at a stop light. I poked around online and discovered that is pretty common a followed clean your IACV suggestions...

Hey guys, so after 8 months in school I am finally reunited with my beautiful prelude, which has been sitting in a dark garage while I was gone ;( Anyway, there was a couple problems still existant when I came back (because apparently the magic car fairy didn't fix them). My dashboard lights...

Hey guys, i'll just start off by saying Hey, my name is Cody, and im new to the site and preludes. I just recently bought a 95 prelude si for $1300 this past weekend. It was originally my buddies car that has been sitting for the past 2 years. Well I got it running, changed the oil, coolant...

So I have a 1988 Prelude, 5 spd. For some reason, it likes to idle real low, but I don't have an IACV or a MAF sensor, for I have a throttle body (carburetor). It occasionally, gradually picks up back to about 1400 rpm, but most of the time idles at about 100-150, maybe 200 rpm. I don't see any...

I apologize for posting about idle surging again, but couldnt find my problem. I have a 92 F22a prelude. As another thread explained, "place finger over bottom hole inside throttle body. When you have suction on it the idle goes back to normal. Problem lies with your FITV (fast idle thermo...
