lmdew Posted June 19, 2015 Share Posted June 19, 2015 Do you smell fuel in the exhaust? Could be you have a leaking injector and it's flooded. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 19, 2015 Share Posted June 19, 2015 when you replace a TPS, isn't there a 'learning' sequence or something? Like, you have to start with a cleared ECU and allow the car to idle from cold or something? Link to comment Share on other sites More sharing options...
desertsubaru Posted June 19, 2015 Share Posted June 19, 2015 When you Cleaned the iacv did you also clean where it goes into the throttle body. It can carbon up causing the IACV not to work correctly. Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 19, 2015 Author Share Posted June 19, 2015 Iacv on my model goes into intake manifold but yes I did same sysptoms. I'm going to have to look into tps learning makes sense as to why it wouldn't start this morning at all had to take the wifes legacy Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 19, 2015 Author Share Posted June 19, 2015 Injectors throw codes right? Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 19, 2015 Share Posted June 19, 2015 Not if its stuck open or clogged. Did you replace the 2 wire temp sensor? Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 19, 2015 Author Share Posted June 19, 2015 I replaced the one under the intake manifold brown connector passenger side Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 20, 2015 Author Share Posted June 20, 2015 So I figured out that my spark wires were shot thought they were new I was wrong. Also tested tps it was faulty so getting another one Monday I'll let you know car starts better but idle is super funky Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 24, 2015 Author Share Posted June 24, 2015 Ok I'm still stuck got four codes pop up changed no. 16 fuse under dash codes went away still won't start right. Link to comment Share on other sites More sharing options...
Razorthirty Posted June 24, 2015 Share Posted June 24, 2015 And the codes are..? Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 24, 2015 Author Share Posted June 24, 2015 Got new codes 31 (tps) 32 (temp sensor) 12 (starter switch) 24 (idle air control) I'm getting frustrated and annoyed. Please if anyone has had this problem. Replaced tps replaced temp sensor cleaned iacv. So car starts then dies if I hold throttle open it starts then idles fine revs fine but as soon as I try to go anywhere it bogs down and acceleration is sketching and speratic. After I get it going when I coast and the rpms drops it drops to zero and trues to dies hitting the throttle and feathering keeps it going then it idles fine again. I know this is a long post. I replaced the spark wires not the plugs. I know ignition coils are fine no. 16 fuse was a fluke I think cuz it was fine. I hear a whiring when I drive or hit throttle vacuum leak? Pcv clog?.

1 Lucky Texan Posted June 24, 2015 Share Posted June 24, 2015 well, a vacuum gauge might tell you something and is cheap to try (mybe free if you 'loan' it out from a parts store) Seems like there could be a wiring or grounding problem. Also, I THINK a couple of those sensors assoc. with those codes use a 5V reference signal from the ECU. If one sensor is killing that, it could affect the others that use it. maybe there's a common ground or a rodent-chewed wiring harness or loose connector? the noise could be a poorly seated airbox after a filter change.

subiphoenix89 Posted June 24, 2015 Author Share Posted June 24, 2015 After closer inspection there are two bolts missing on air box just drove to work 30 minutes or so at 60 plus miles the whole way car starts right up no stutter or hesitation while driving slight idle surge almost unnoticeable. So I'm dead set on vacuume leak that is closing due to heat expansion. Please correct me if my thinking is just all wrong maybe intake manifold because its metal to metal with gasket of course.

subiphoenix89 Posted June 24, 2015 Author Share Posted June 24, 2015 Also cel disappeared and I'm sure will come back when I start car after work when engine cold Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted June 24, 2015 Share Posted June 24, 2015 one way to try to locate a vacuum leak, is to spray around with carb cleaner. Intake manifold, vacuum lines,etc. When it gets sucked in, listen for change in the idle as it is burned with the fuel. 1 Link to comment Share on other sites More sharing options...
grimaceNMike Posted June 24, 2015 Share Posted June 24, 2015 How did you remove your maf? If you try to remove it buy taking the 4 small screw's out and pulling on it you can break something. Link to comment Share on other sites More sharing options...

subiphoenix89 Posted June 24, 2015 Author Share Posted June 24, 2015 I knowe about the carb spray method just trying to avoid it Cuz it can be very dangerous how does the cigar trick work? Where would I blow into on my car to get it to go throw all the air ducts? Link to comment Share on other sites More sharing options...
subiphoenix89 Posted June 25, 2015 Author Share Posted June 25, 2015 Fixed it it was my intake manifold driver side bolts very loose Link to comment Share on other sites More sharing options...
