For some reason my car is idling about 200 rpms lower, and it doesn't usually want to start, when you start the car, the rpm's immediately fall down to around 500-600, and with the cams, it struggles to keep running. Sometimes it just plain shuts off. This started happening the day after I filled my tank and fixed all the boost leaks on my intake. Does anyone know what the problem could be?! The low rps idle is too rough... Could i have anything to do with being tuned with a boost leak?

 

1. Test for, and fix boost leaks
2. THEN get tuned
3. ?????
4. Profit

 

I didn't have an option. My car was running too lean and it's my daily. Plus I didn't realize the plugs on my intake were messed up.

 

It wont make that much of a difference. Are you recirculating the bov?

 

Check to see if the MAF is clear of debris
What are the mods?

 

how many miles on the car? it could be the erg stuck open

 

No codes other than the usual...

 

There's no EGR on the car.

 

u said something about cams, which ones do you have?? Cause some cams are really rough and idle really bad unless tuned

 

Kelford. And they are tuned, they've been in the car for a while. This problem just randomly started as of Thursday night.

 

check all the vacuum lines

make sure the MAF sensor is plugged in all the way...remove the negative battery cable and reset the system

 

I'm gonna try the battery cable method, cause everything else checks out. I notice a cable that I had notice wasn't grounded when I had fixed the vacuum leaks and I can grounded it properly. Well, when ever I play with that, the problems get worse. Not when I first start moving the car, it want idle surge, hard... Until I let the car set and surge for a good 2-3 minutes, then it settles around 1800rpm and slowly over time lowers to 1100, which is where it needs to be. He's a pic of the cable, if you guys can identify it.


It's between the fuse box and the master cylinder.

 

Can you tell where it was hooked up? Where does the other end connect? A ground that big not connected would for sure cause problems.

 

The problems started when I hooked it up. lol It's a a grounding spot on the apron area by the fuse box. If needing, I'll get a pic.

 

Guys! Problem is still there, just getting worse. It just wants to idle at 2k, then pulse from 1600 to 2200 rpm for a minute, then back to 2k. I've notice that it seems to stop when I get the car above 10mph and stop the car with the handbrake. I realize it sounds stupid, but it's not a lie. Also, is nobody able to identify that wire. I've tried every suggestion, I'm tired of the poor drivability and wasted gas.
