Hi guys, I know there's lots of IDLE threads, but rest assure I looked before posting this.

OK, So I noticed when the car idles, the RPM guage seems to move up and down a lot, below 1000, then up to 1000, below a bit. Seems finnicky. It never really did this before I installed my Steeda SRI. It rested at a constant figure before.

I also noticed before AND after the SRI install that the car seems to bog and shake when stopped at a light, does it for a little bit, goes away, then comes back.. This normal?

Thanks guys!

did you reset you ecu after you installed your SRI? if not unhook the neg battery term for like 10 mins then reinstall it... go for a drive and the ecu will relearn itself.

From the Owmer's manual:

Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance.

To begin this process:

1. With the vehicle at a complete stop, set the parking brake.

2. Put the gearshift in P (Park) (automatic transaxle) or the neutral
position (manual transaxle), turn off all accessories and start the engine.

3. Run the engine until it reaches normal operating temperature.

4. Allow the engine to idle for at least one minute.

5. Turn the A/C on and allow the engine to idle for at least one minute.

6. Drive the vehicle to complete the relearning process.

• The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.

• If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.

When the battery is disconnected or a new battery installed, the
transmission must learn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will fully update transmission operation to its optimum shift feel.

Yeah, I drove for about an hour after installing it actually, but the thing is the car still bogged and shook a bit even before the SRI install.

make sure the intake is tight on the throttle body. also be sure that the connector is on the MAF sensor really good. either one of those could cause the symptoms. i never reset my ecu after my intake install and didnt have those problems. however when i went from a SRI to a cold air i didnt get the MAF plugged in all the way and it did exactly what you described.

So is this on the '09?
If so bring it to the dealer and let them deal with it, after you take the SRI off of course.

oh its an 09. yeh go with what he said. take it back to all stock parts and take it to the dealer to fix it. if you show up with any mods on the car tho they will throw a fit and not fix it.
