Z went into limp mode in the rain tonight. There was no cell but I did the ecu reset procedure and it went away but then when I drove a couple hours later it did it again. I did some research and common problems were the throttle body and the ss box. Is there any way the rain would have caused this?

Thanks in advance

Ps I'm vortech supercharged with plenum and 3.12 pulley

 

I can't really say what's going on with your car but moisture got into my ignition system because of all of the rain and blew 2 of my coils. I'm Vortech SC'd too.

 

Do you have a stock hood? And my Tuner was having the same problem with my car! I'm gonna sell my SS box and get a Utec.

 

My car has been going into limp mode, but I belive it just my thottle body getting tierd. You can buy a redone throttle body at some nissan dealers for $150. Supercharged just bought one for his G not long ago, or ebay has them for $99. Easy fix IMO.

Never heard about this before. Anyone else have this problem?

 

This problem is more commen than you might think, do a search and you'll be surprised on what you'll find on this issue.

 

Just did a search and I'm surprised myself. Is it normal that there is no CEL though? And is there any way to be sure its the TB?

 

There might not be a CEL light on, but if you don't at least read the stored codes in the ECU (before resetting it), you won't have a clue as to what caused it... Cipher is a great tool for this kind of thing.

 

hmm, when my car went into limp mode, you most definately couldnt clear it with the pedal ecu reset. i had to unplug the battery for a few hours. and even that had to be done 2x.

Consider yourself lucky, that you could reset the ecu easily and have it run.

 

Yeah, I have the stock hood. Your car doesn't have to be modded to have this problem. My friend's bone stock car had this problem too. Water got into his ignition system too. The car started misfiring and it was because he blew a coil.

 

well the car I'd now going into limp mode whenever I accelerate even semi-hard, I keep resetting it cuz I need to get home from la, the cell came on once but I cleared it so I coal drive I guess I'll hope for it to come on again... The only time I'll ever want it to

 

so whan you say limp mode, your car wont rev past 2k and wont go over 20 mph?

something is seriously wrong. i wouldnt just keep clearing codes and continue to drive it.

 

You can go over 20mph in limp mode. You just can't rev past like 2500

 

That's weird that your car is going into limp mode but no CEL comes on. My CEL came on right away when my car went into limp mode. I got the P0300 code.

 

Im on my 2nd throttle body... 1 before my supercharger and just recently (2 months ago)

 

Would the throttlebody's go bad if we use the coolant bypass? don't most aftermarket plenums have the coolant bypass?

 

you might want to check the big rubber grommet on the passenger side behind the battery. When I got my car the grommet had been pulle out and not installed properly so when it rained a ton my car would go into limp mode and would barely stay running.

 

Car is FIXED!!!! Okay so the idle was fluctuating on the car a lot even when the car wasn't in limp mode... So I decided to do all procedures on this page.... Right after I did it the car is fine again and the idle and throttle input is much smoother....

I'am glad all is OK!

Just so you guys know I just bought a redone Throttle Body for $150 at the nissan dealer. No need to buy a new one at $450 plus.

Just a heads up for you guys that might be needing one soon.

 

^ Saw a brand new one on ebay today as well, it was listed for ~$250 IIRC
