AEM SRI problems(?) when in traffic

[mopiko]

This morning I was driving to work and got stuck in traffic for 2 1/2 hours....

after more than 45 minutes of stop and 1st gear go I've notice a very bad hestitation when I engage my clutch.... Engine feels like a rich mixture of A/F but my A/F gauge is dead on 14.7. Is this a nature of AEM SRI?

BTW I have a 2003 5-speed Protege5 with no other mod but that. (Well and the A/F gauge and oil pressure gauge and TEIN spring dropped with front lip)...

Thank you for your help...

Have you tried resetting your ECU? Disconnect negative battery terminal, step on brakes for 10+ seconds to discharge the system. Leave it unplugged for 10 minutes to be sure and reconnect!

BTW, I've never had that issue, so thats my reasoning .

[yay for cars]

just an idea...
people always talk about how with an sri, the only bad part is that while not moving, it takes in hotter air. maybe in traffic, it was sucking in a lot of hot air from the engine bay and thats what caused the hesitation?

humm... could be. Well right now I'm working and my car is parked nicely cooled building basement til tonight I'll see what happen than. Any other inputs?

Oh thank you both BTW.

Your af meter shouldnt be stuck on 14.7 when stopped it should be moving back and fourth adjusting itself. The only time my a/f meter stays stuck in a position is when I am revving high and when I am on the highway doing about 75 and up and then I run extremely rich. One of my next plans after iridium plugs and grounding kit is to gat the ractive fpr and lean it out a little bit. You still shouldnt be stuck at 14.7 when just sitting their or part throttle.

stopping it reads 17, and when I first engage the clutch and move it go lean a little than back to 14.7

BTW I drove home after work and all is well, I guess the hot air in the engine compartment contributed to this.

It's pretty decent but as you've reading this whole thread there is potential problem with you get stuck in traffic as the filter is located directly behind the fan. I'm planning to reverse back to stock and than getting a CAI as I've found myself in traffic more and more and this problem presist in hot weather.

So if you want I can sell my old one to you.

Do you have the intake inlet (i.e. filter) "down" in the engine bay - behind the radiator? Someone on here had modified the intake slightly and rotated it 90 degreess so the filter is sitting over the hole in the fender (through which the Injen CAI runs).

Here, I found the pics:

I am tempted to CAI, but I would rather have easier access to the filter, but am unsure if the ~$40 difference is justified in one direction or another. Just thought this might spur some ideas for solving your issue.

No problems here. Not even in traffic. I've had it for about 5000km's now.
