[alexbonneau]

Hi , Im new on this forum and excuse me , i dont speak english , im french from quebec canada , i have a gst 1998 and i buy this car 2 year ago ... i have a #$%? trouble with ... i have no torq on the start ... when there is a stop in a slope ... is very hard go on , the motor choke or i slip the clutch ! But when i run normaly on the road its okay ... i have the feeling that the power is not same all time ! i think the engine is stock , i dont have dsmlink and i have a k/n filter ! I know it's hard to diagnose, but maybe someone had the same problem as me !!!!

Thanks

Alex

I'm sorry I don't understand the problem

Car is slow to accelerate when driving up an incline, or driving up a hill ?

Or are you saying that when you are at a stop or stop sign, on the hill or incline, you release the clutch and the car died?

On the hill to start accelerating you should press the gas pedal harder when you release the clutch

Have u done any recent maintenance like plug and wires? Also if the problem only appears while under load then I would encourage a boost leak test.

I replaced the spark plug last summer but not the wire! , Chrysler kid, I have the same problem when I climb a slope or when I leave a stop! I sometimes feel that these an air / fuel problem! I have to give a lot of gas to leave ... but as I said, when I ride normally and I want power ... there is, but I have the impression that the power is not always equal! ! Sorry guys i use google translate ....

+1 boost leak test.

I forgot to tell you, when I ask a lot of power and I have to slow down quickly, sometimes the idle is very low and sometimes the engine stops ... maybe there is a link. ..! And when I installed my filter k and n, I had to remove the aluminum stuff in the maf because the engine did turn well!

Judging from the picture you've got some td05 turbo whether it's a 14b 16g etc hard to say witrh out measuring the wheel. You've got a fmic and you've got the bov recirculated which is good.

The aluminum stuff you took out was it the honeycomb? If so that will cause some drivability issues because it is there to straighten out the airflow through the sensor to accurately read the airflow. How much it effects it I'm not sure

 

[alexbonneau]

Thanks Brian, yes these honeycomb-shaped stuff, the problem is that when I installed my filter k / n, if I left the grill honecomb, the engine was not doing well at idle, if I removed it completely these same thing, so there are just half, I would like to keep my k / n and put the fence but the engine goes wrong ...

I think you should access your throttle body and clean it. If it's built up with junk, it can cause issues mostly at idle and low rpm. It's free and a good place to start.

 

[brian9397gsx]

That's strange that having the honeycomb in would cause an issue it's usually the other way around. It's deff not a bad idea to remove and thoroughly clean the throttle body but if it started after the k n install I doubt that it. More than likely the mas needs cleaned which everyone has their own opinion on. It seems like you have an airflow issue everything is connected no loose couplers and you've performed a blt?

Karma vortex mas air sensors you do not clean. They operate on entirely different principles than a hot wire mas which does require cleaning.

I have the same intercooler kit, and the blow off valve was very bad quality and when I looked at it I found it was bad inside

Bad one on the left

There is something wrong with your maf. There may be some air leaking from your clamps, the throttle body, or any of the gaskets and couplers. It could also be a combination of a few things. Try a boost leak test then message back to us.
