Loss in acceleration + throttle response ??

spearfish25 · 07-11-2010, 08:13 AM

FWIW, when I started adding Techron to my tank, my fuel gauge started reading crazy. It took about 5 tanks to get the gauge working right again. Maybe unrelated, but that stuff isn't going in my tank again.

Very interesting. I never had that issue.

I noticed the exact same thing when going from shell to techron, never again

I've been dealing with this situation ever since I purchased my Z back in June of this year. My car is bone stock and has had one oil change so far but I noticed the delayed throttle response/loss of acceleration about a week after I got it and has continued to do it up until now. It typically does this when the car is warmed up (oil temp 230-240), but I'm really surprised no one has determined the cause of this yet! I'm taking the Z into Nissan tomorrow to have them investigate this problem so hopefully I can get some sort of answer..

So far I believe it is already known that the ECU starts holding back power when the oil temps go beyond 200F. I just hate it when the car ramps up slowly in 1st every once in awhile regardless of oil temps.

Ahhh alright, I must have missed that. I thought I read the entire thread lol. So would you say an oil cooler is a necessity if I live in Phoenix, Arizona? I can't take it when my car starts to do that, which is almost every day. My average oil temps are 220-230F

Definitely take it in. They likely wont' do anything (ECU reflash if you're LUCKY, but that probably won't fix it). But they need to know about it. If this ever gets resolved, I'll buy another one =)

I'm gonna do my best to make sure everyone that needs to know at Nissan hears what I have to say. It's unfair that I have to deal with an ECU that puts my car in limp mode purely from daily driving. Hopefully when this is all said and done... OIL COOLERS FOR EVERYONE!

Just picked my car up from the dealership after an oil change and maintenance check up. I drove across the street to Wendy's and my clutch won't come back up after I press it down to put it in gear.... WTF! Dealership is about to come pick my car up and tow it back so they can see what's going on. My car has 10,600 miles on it. Anyone know what this could be? They also said that the delayed throttle response is due to the ECU and that's just how it's programmed. Not much help

Master and/or CSC failure... had mine replaced as well. Master tech also says it has to be ECU programming and mentions emissions compliance. It pretty much kills the fun factor.
