Idk the guy who tunes my car said its fine and just to floor it when it doesn't want to start and he's one of the best mustang tuners in Houston

 

Personally I think it's tune related. But I don't know much about anything.

Is it dumping fuel into the cylinder and you have to rev it to burn it off? Do you have LT headers? Are the rear O2 sensors turned off?

When the car starts up it only takes a few seconds for it to start reading the O2 sensors for air to fuel info. When it doesn't get what it needs it adds more fuel to cover its own ***.

I was told there is some mapping in the computer to control the air to fuel before the O2 sensor readings take over. My tuner increase the time this mapping sends the info allowing for the O2 sensor to warm up and begin sending the correct info. After that the car started much easier and stopped throwing O2 codes.

Just an idea.

 

I think it has to do with my tune also I guess I just need to take it somewhere else .. I do have LT headers and he did say something about it having to burn off the extra fuel .not sure whats going on .. I really like Strictly Performance and trust him but there is something wrong here that he's not seeing I guess.. So much for being the best in Houston

 

Try Patrick at PSI in Webster.

 

Ya I've heard about them. WSM (WestSide Mustangs) use them all the time... Guess that's where I'll go next. Richard said its something I have to deal with cause I have a high performance car

 

I don't think so. Engine heaters are for continuous way below freezing - like where Nathan lives. lol

Somethings off with the fuel setting IMO. Its like a carb engine where the choke isn't closing on initial startup. You're not getting a rich enough mix at cold start. So you're countering that by flooring it when starting (normally a no-no on fuel injection), then you're blowing all that excess fuel mix out the pipes.

Would a problem with the MAF be a cause? Or is it in the tune?

 

I'm just going to get it re-tuned

 

Be sure to tell the tuner tue experience you are having in detail. It's one thing to tune it and another thing to turn off or on certain sensors that might contribute to your problem.

 

Don't mean to get off track, but is my thinking correct that a dirty MAF wire can cause these type of problems? Still learning this computer stuff.

 

A dirty MAF sensor, a dirty throttle body, and a vacuum leak all seem to be common problems that can be corrected at home.

 

Dirty stuff

 

Can my intro thread get 100 posts???

 

I dont know why not?
