I have a 2004 Chrysler Crossfire limited MANUAL
Bought it about a month ago
114,000 Miles
Needwings air intake
flowmaster exhaust
great driver, and I put 1000 miles on it in the first week,
as I was driving I was banging the gears and pushing the pedal to about 90%
and as soon as I hit fourth it bogged out and slowed down until it stopped and finally shut off.
I turn it back on and it starts just fine but now it’s sputtering and puttering something fierce...
I’d say a good 50% loss of power
take it to all the parts stores for a check engine test..
i get
P0171
P0171 confirmed MAF sensor, O2 sensor, pcv, leak unknown
p0221 TPS Faulty
p0174 bank one, bank two running lean

so so I take it to Chrysler, hey these are codes help me out...
thay try charging me 700$ +160 for labor. For ONE O2 sensor......

take matters into my own hands.

Replaced o2 sensors in both bank one and two
took apart THROTTLE BODY cleaned it ,
cleaned MAF sensor with only MAF cleaner
put it all back together.


Still have a lack of power (running at 70% total power is my guess)
Idles a tad rough but not extreme,( I’d say a 3 out of 10 in roughness)
And when I hit the gas there’s no get up and I hear a whistle when I hit about 2700 or 3000 ish, or if I try to press a bit more liberally on the pedal it does it as well .
codes P0171
p0171 confirmed
and P0174 are still present
but I removed the p0221 code


NOTE: Im going through gas exponentially faster as wel..

if if there is any particular direction I can be guided in as to where I should take my next steps I would greatly appreciate it
after that chrysler experience, I have a very rough time taking it to anybody...
