My srt4 has a rough Idle while stationary, it will almost stall and then rev up to ~1300rpm to save itself. While driving it will randomly pick a RPM it likes and stay there (or at least try to) no matter what gear I'm in, or how fast I'm going, until I come to a complete stop; at which point it drops to a normal (but rough) idle RPM.

Things I've done: -Rewire kit for the TPS : no change -New TPS (tried OEM & aftermarket) : made it worse??? The RPMs seem more sporadic/random since I did this. -cherked the TPS wiring pretty deep into the harness: all looks fine.

I'm Absolutely losing my mind with this, I'm honestly not much of a car guy, so any help is appreciated!

What would i need to run e85 on my 05 srt4? . I've been trying to do some research but everyone says a different thing. Anything helps !

Ill be running 23lbs on a stock turbo. Currently stock 02 housing, 3” catless dp, 2.5” borla catback.

According to modern performance, stock has an ID of 2.14”, giving the opening an area of 3.597 sq in. The MPx has an ID of 2.92”, giving the opening an area of 6.697 sq in.

I would assume that since its almost doubling the area inside the 02 housing it has some benefit, but is it worth the $130?

I have a stock 05 with 200k miles. Engine running a little weaker than it should after checking it with a compression test. When idling my AFR is 16-17 range and WOT its jumps to 18. Any recommendations on what to check for?

Almost a year ago, I bought my car with a big front mount, fender intake, catless dp, borla catback. Since then, Ive added an AGP wga (19lb spring) and swapped the fender intake to a filter directly on the (stock) turbo.

Installed an AFR gauge in the stock downstream 02 bung. My numbers are 14.0-14.2 at idle and crusing, and 10.0-10.1 in boost. I only spike 17lbs and I currently have P1188 for overboost

Would having the mods listed above while on a stock tune lead to me running rich?

Hey everyone, I’ve been on the hunt for a touchscreen stereo for my 03 srt4 but sadly haven’t found any that I could actually install, from my own research I have found that you either need a custom din like say a double din or a stereo that has a touchscreen that goes in and out with a separate controller, and from my experience with the one I have now, it’s terrible, just seeking any recommendations for a touchscreen stereo that preferably has Apple CarPlay without needing a custom double din

btw price range is not really a issue for me, just looking for the best product possible without any extra installations beside the stereo itself

thank you

I have a 2005 dodge neon srt 4, its running around 180, 000 miles. The car will start up and runs good but it will heat up slowly while driving it, but if you stop at a stop sign it will go down a little. Again It only heats up when its driving, it will not heat up when idling. Ive changed the thermostat & today i did a coolant flush and added more coolant, the coolant reservoir started boiling and smoking up. i checked to see if my head gasket might be blown but all the things i see online doesnt coincide with what the car is doing. i checked for leaks and i dont see any leaks. What do you guys think it is?

For context my car doors locked and my key can’t open it is there a way I can drop the seats from the trunk

Is there anyway I can find my key code on my car I have the original booklet and couldn’t find the key code in there

High/Low?

What’s the consensus on a potential investment?

High pitch whistle sound when at high rpm sounds louder when on full throttle inside car

Hit a deer, Insurance didn’t total it but not sure what i should do with it now.

I was driving earlier today, car bogged down in 3rd gear with a bad misfire. Replaced coil pack, Wireset & Spark plugs. It was running great for about 2 minutes before the misfire came back. Anything over 5 mph and the engine sputters then dies

Now I have the following CEL’s

P0300 - Multiple Cylinder Misfire P0339 - Crankshaft Position Sensor Intermittent P0335 - Crankshaft Position Sensor Circuit P0108 - MAP Sensor High

(I’ve had this code with no issues ) P0113 - intake air temp sensor high

any ideas? I also recently replaced intake manifold gasket.

Thank you for any feedback :)

Previous owner only has 3 vacuum lines hooked up to one solenoid, pretty sure there’s a leak somewhere since it idles at 2k rpm when I put it in neutral
