Having hesitation issues. When the throttle cuts out its not because I'm letting off the gas. If I continue to give it gas it hits a wall even harder and wants to stall. Any ideas? I've tried many things to fix this issue so any help would be appreciated. Tps is reading correct values btw.

 

First things first, pull the codes and see what the car is telling you is wrong. Usually a good place to start.

 

Can we get some more info on the car? Mods? etc.

 

Sorry for the late reply. Car is a 93 jdm type rz. It has a power fc, all sensors check out and same with tps sensor. It's non sequential converted. I have it down to 5 or 6 vacuum lines for the turbos n stuff. Has a re-a downpipe (jdms come stock with down pipe). Supra fuel pump rewired so it has consisted voltage. Think it a trust or greddy air filter. Have changed various sensor like o2 and h2o temp.

On a side note the car drives pretty good when it's cold. All it takes is a few blocks and it starts hesitating like that.

That's all the main stuff off the top of my head. Car has always had this hesitation although it has randomly disappeared for like a month. I think it's back to stay until I figure out the root of the cause of the issue.

 

what vacuum do you read at idle? how much boost can you get up to before it cuts off?

 

I can get near full boost. Don't have boost leaks. haven't checked the vacuum at idle, care to explain what that has to do with hesitation?

 

Did you ever get it sorted out?. What was the issue?
