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...

 

You running good premium gas?
Do you have a vacuum gauge ?

 

See my sigline!

 

yeah I dead put some safe cleaners into the tank and some high octane booster to help in the last few fill ups, but, I do no lt have a vacuum gauge

 

check the valve cover breather hoses, if they are old brittle and cracked it can cause these issues, there are 3 hoses to check.

 

Are these the hoses that sit above the throttle body and go into them?

 

yes that is 2 of the 3. the third is the larger hose from the drivers cover to the MAF housing on the back of the engine

 

All of these hoses look to be in good condition

 

When you cleaned the throttle body: did you replace the large "o" ring? You seem to have a vacuum leak as Needswings indicated.

 

Yes
