anybody have this problem? - SRT Forums

lil_hub_cap · 11-20-2009, 02:42 AM

alright well heres the thing, my car idles just fine, but occasionally i get a weird surge in power when im just casually accelerating, and then ping code pops mentions the MAP/TPS somethin. (ill post the actual code tomorrow when i read it)
so i figured it was the map sensor, so i replaced the map and rewired the connector, and i figured it was all good. i tested the car 3 times, and took it up to about 140 at WOT. today i was cruising right around 60 slowly building up, and ding the code popped again. pissed me off and started searching around, and found this 03-05 SRT4 owners - Have Check Engine Codes P0121, P0122, P0123 ? Have weird idling/Throttle issues? Modern Performance’s Blog
anybody think thats actually whats wrong or any ideas?
id appreciate it

alot of the problems you come across are already answered on the forums. Stop being lazy and search.

But you need a TPS rewire kit

ptb..

lil_hub_cap · 11-20-2009, 05:16 AM

i did search for about 20 minutes and encountered nothing, so i figured id ask. i wasnt sure if that kit was a cure for a legit problem or not.
and whats ptb?

Part throttle boost....

1srt4_2nv · 11-20-2009, 07:13 AM

go out and start your car, then play with both the wires(in the pics there a white sensor on the bottom of the TB,right below the red markings) top of the TB and below the TB, then you know which one you need to get

lil_hub_cap · 11-20-2009, 02:57 PM

the thing i cant figure out is that the car idles just fine its only when im at PTB

coors · 11-20-2009, 03:00 PM

just try to not ptb to 4psi for long periods of time.

coors · 11-20-2009, 03:00 PM

you should be getting a 1188 code

lil_hub_cap · 11-20-2009, 03:47 PM

yeah im still not sure what the code is honestly, i havnt had a chance to plug into it yet.
but im pretty sure the car should be able to ptb for long periods of time with no problems.

coors · 11-20-2009, 03:59 PM

you can do by turning the key 3 times

lil_hub_cap · 11-20-2009, 09:13 PM

yeah ill just plug the ethos into it and see what it says. does the tps sound like a resonable problem for it though?

rapper8521 · 11-21-2009, 06:46 AM

just and fyi...may not be the issue, but if you havent had it dont already, check for an ECU flash at the dealership, and check ur plug wires...

lil_hub_cap · 11-21-2009, 04:31 PM

its possible, but ive had the ecu fashed for my turbo kit and everything. and it just started acting up recently. plug wires are MSD and resistance wise there right where they need to be so idk really

lil_hub_cap · 11-25-2009, 02:52 PM

well as it turns out, i believe i have a leak in my throttle body. i hooked it up to a smoke machine, and smoke flowed out through the spring bearing. so i purchased MPx 62mm so we shall see
