Re: 96 civic hatchback dies when giving it gas

Re: 96 civic hatchback dies when giving it gas
So you made all of those engine changes and haven't got tuned yet I assume....?

Saturated or peak/ hold injectors?

Re: 96 civic hatchback dies when giving it gas
i have a resistor box installed and got a base map chip from phearable,the tps sensor was at a .08 so i moved it down to a .05 and i now i can give it gas,but the problem now is it won,t start unless you put your foot on the gas pedal

Re: 96 civic hatchback dies when giving it gas
The base map is probably crap. Probably have a sensor problem also, likely MAP. That bigger throttle body will cause all kinds of problems without a good tune though. The flow will be wrong for the TPS reading.

Re: 96 civic hatchback dies when giving it gas
yes sir^^ the throttle body is to big causing rich problems,and the hole on the throttle body for the map sensor was exposed but im confused bout the code 21 vtec solenoid

Re: 96 civic hatchback dies when giving it gas
Its gonna be even more harder to start as you flood the cylinders with unburnt fuel. switch to stock injectors and stock ECU or map. See if it will run with that

Re: 96 civic hatchback dies when giving it gas
thats what im working on now laser

Re: 96 civic hatchback dies when giving it gas
ok update.....got rid of the check engine light and drove car,car drives fine but when you stop it dies and at idle surge 200 rpm to stay under a 1000rpm and will start right up after cutting off...i went with stock injectors and and a ls stock throttle body the coolant lines under throttle body left open but i dont think thats the problem
|
Re: 96 civic hatchback dies when giving it gas
Are the coolant lines to the fast idle thermovalve connected? Is the behavior changing depending on whether the engine is cold or hot? Does the LS throttle body have a different TPS than you used before?
|
Re: 96 civic hatchback dies when giving it gas
yes it has a different tps sensor and no coolant lines connected to throttle body and it doesn't matter the weather cause when i drove it home from work idle acted the same...on my throttle body it's just lines no fast idle mechanism
