I have a 2003 acura rsx, base model automatic. I've been having a idle issue and I believe it has to do with the map sensor wiring, please correct me if I'm wrong. Car idles at about 1500 rpm, but if I disconnect my map sensor the car idles where it should. I've already changed out the map...

Sorry, I honestly tried to google up the answer, but no luck. Got 2002 base rsx. All in all it has no major issues for now except one: when driving in a traffic jam it is often too fast on 2nd gear at idle, and when I switch to 1st I struggle to maintain constant smooth low speed. When the gas...

My car is the Base RSX 2003, 5spd. I noticed this today, and was wondering if this is normal or not. I was idling after a 10-20 minute drive, parking brake on and transmission in neutral, and rpm was around 650. When I blipped the throttle, it would rev up to 1500-2000rpm, and then dip down...

Alright I need someone who knows a little more than me. 04 rsx type s. Oem ecu no Boltons Drove through some pretty deepwater last Thursday. Never cut off got home no problem. Friday I start the car no issues but left it parked. Today I go to start it and it spins but doesn’t crank. I hold it...

This might have been a thing that ive had for a while but i started to notice my headlights, taillights and some of the dash light have a very slight flicker or pulsing going on.. Brought it to my guy at the shop and he said that batter was fine, i think he either said 12v or 14. But now as for...

I have a base 2002 model with a surging idle from 900 to 1900 and back. It's coming up with 2 CELs, p0505 and p1505. So far I sprayed for leaks, cleaned the throttle body/ICV, changed the PCV valve. I would appreciate any type of help and direction.

So I installed a universal catch can on the weekend and when I went to drive the next the day it idled a lot higher (2k) and threw a CEL, I also had to add a liter of oil because it was pretty low. The catch can has two ports, I fed one through the PCV valve on the left side of the engine, I...

was driving home and as i pushed in the clutch to pull in the driveway it died. so now it idles at around 6 or 700 cold and then 500 after it warms up. if i rev it it will go all the way down to 3 or 4 then back to 500. p0505 code air idle control valve. but i changed the air idle control valve...

i just noticed today that when i turn my A/C on at idle, there is a tapping/knocking noise coming from the driver side of the engine bay. it also goes away when i push in the clutch. is this transmission issues? i just bought this car and it only has 77,000 miles, it’s an 04 rsx type s

I have a 02 RSX type s with a 04 tsx motor and I was told ecu matches motor. My question is the throttle body doesn't match up right with intake. I have replaced tps and everything went great for about 100 miles then iacv cel popped up. Tried cleaning it up myself and that didn't work. I can't...

Does anyone know what this sound might be? The car was fine when I drove to LA with some traffic. But on the way back, it made the noise 3 out of the 20 times I was idling on the streets/gas station and then started to overheat in fwy traffic. Noise: https://youtu.be/F8TvAny_rRw I worked on it...

This car has been an absolute royal headache for some time now. Anyways, it’s a 2006 type S. K20A2 bottom end with the K20Z1 head. I rebuilt the motor with all the main ‘wear’ components (rings, main bearings, rod bearings, valve stem seals, gaskets, etc, etc,etc.). Anyways, day number one of...

Ok so it all started one day when I just drove and stalled at a stop light. I thought it was me at first but then it happened again. Then I noticed the battery light was on. So I checked the battery and it was fine. I cleaned the throttle body and the car seemed fine. But then clearly it wasn’t...

Update 4-10-19 (~5 months from issue) idle still running perfectly well. 2006 Acura RSX Type-S - MAP sensor code is the only code seen, and this appears sporadically I apologize in advance for what has become a saga to behold. My dearest sympathies to anyone that has the courage to read and...

Having some issues with my 02 type s, having some grinding noise coming from the transmission area while the car is at normal operating range at idle. I've had a bad TOB on my 06 type s and these were not the same symptoms i previously experienced. Here is the link to my video, you can clearly...

2003 Acura RSX Type-S 213K mi The short of it: Idle works fine for a minute after vehicle is started, then fluctuates rapidly between 500 and 3000 rpm. Long story: Recently replaced a bunch of stuff, alternator, starter, all AC devices, coolant. After I put it back together, car ran fine but...

Hey guys, new to the forum and rsx's, actually never owned a honda at all before. I've done a fair bit of searching and so far I plan to clean the IACV and throttle body. I'm reasonably mechanically inclined but don't know alot about tuners, more of an oldschool non computer type guy. Anyhow, I...

Sorry I know there’s forms of this but i have 04 manual trans base type with 150k miles & my car keeps overheating on idle. I checked under the bottom and something is leaking I think it’s coolant and there no sounds out of the ordinary and I recently took of my throttle body to clean the ICV...

Story Time: Recently, the RSX went past 150k miles and I took it in for a tuneup and 150k scheduled maintenance. The RPM has been going up and down from 1200 to 500 RPM during idle. It is supposed to be at steady 850-950, but it kept going down below 500 and it almost shuddered to a stall after...
