Regal Turbo
Over the last 2 or so months i have noticed random misfires every once and a while, along with a loss of power and performance. Finally the engine light came on, spitting out the p1101 code which is a performance intake code. When I looked up the code it had said MAF sensor issue, but when autozone printed out the sheet for me it said probable cause was the turbo intercooler (not sure how accurate autozone is). I have cleaned the MAF sensor (I have a new one coming in the mail from rock auto) and replaced both the intake and the exhaust side VVT solenoids. The new solenoids made a big difference, but the car is still putting itself in limp mode upon start up. Other than replacing the MAF sensor I wanted to inspect the throttle body but im not sure where it is or how to get to it because tutorials and forum posts for this car is scarce. I'm not really sure what else to do? Car is at 105,000 and before anyone tells me just take it in and have the dealership do an inspection rather than throwing money and new parts at it, that option is not financially viable for me because im currently in between jobs. Also worth mentioning that it has brand new coil packs, plugs, and air filter. Thanks in advance
 
do you have the awd or the fwd? the fwd is easy to follow, the thottlebody is right by the battery.
Also, try checking your MAP.

the FWD uses a MAF and a MAP.

Can also try to disconnect the battery for about 30 mins, and then let the ECU relearn everything.
 
Did the problem exist before replacing the air filter?

Since the original post I have cleaned throttle body and replaced the MAF sensor, the combination of these two have drastically improved responsiveness and somewhat helped the idle. Idle is still a bit rough and has a very feint gas smell, I bought the MAP sensor to replace like you said and cause the symptoms I have line up with a bad MAP sensor, however I have no idea how to remove the plastic cover that is on the air intake manifold. Can't find any screws so Im assuming its held on with clips but Im still at a loss. I cannot find anything to DIY repair on this car online
 
Did you Google spark plug replacement?
Not sure if yours is like this, remove oil fill cap and pull the cover off.
 
It shows you how to remove the engine cover.
Ohhh i understand, its not the engine cover i have to get off theres a plastic cover on the intake manifold i need to get off to access the map sensor

So you watched the video in the link and your engine is different?
 
What year model is causing the problem?
 
What title? 😳🙁
 

Maybe this will help!

No i think your misunderstand what im saying, i know how to remove the engine cover but thats not what i need access to. There is a seperate plastic cover on the intake manifold on the back side of the engine that i need to remove to gain access to the MAP sensor
 
SOLVED!!! Turns out the map sensor was just below the throttle body towards the firewall! Its a pain in the rear to get to and you have to remove the charge pipe to get decent access to it but overall was a pretty simple replacement. After swapping out the new MAP i disconnected the battery to let the ecu reset and thankfully i can say after replacing the MAP, MAF, both VVT solenoids, and cleaning the throttle body has resolved my issue and she feels like the first day i drove it home! Thank you everyone who contributed time to responding to my questions and trying to help me🙂

I broke this piece on the driver side, my question is which piece is it? It’s on the driver side bottom looking at the car standing in front of it. Do you know anywhere that has them cheaper then $500

I also have the P1101 code and both dealer and mechanic ic stated most likely an O ring on intercooler pipe. But nowhere I look shows an O ring. It shows I have to replace the entire pipe at a cost of $550. Anyone know about this?
