Starting, Idle, driving issue's

[panamarojo]

This is a 91 GSX and I have check the spark and injectors and they seem to be working good. Just got my ECU fixed also. When I get the car started and its idling, if I give it any gas it will bog down and then rev up if it doesnt die. Seems to be lagging. Video of my car. YouTube - Picture 036

What is your fuel pressure at? MAF plugged in?

 

[panamarojo]

Maf is plugged in, has a K&N filter. And I will be doing a fuel pressure test tomorrow. Ill let you know how that goes.

i had a problem with mostly witht the same problems on my 98 gst.. do u get a check engine light? if so get the code.. mine said it was a lean mixture and the second code was a rich mixture.. found out it was my camshaft position sensor

 

[panamarojo]

I am not getting a check engine light tho. My battery has been disconnected so i am not sure if its just not picking one up yet.

whats up with your fuel gauge

 

[panamarojo]

Well after this issue started happening I thought it was the fuel pump. So I took it out and swapped. And the gauge never worked after that. It seemed like the float lever thing on the fuel pump was hard to move.

Ok so here is a video of the hose that isn't connected to anything. My guess it was a drain hose or something haha. And also at the end of the video. That cannister does anything connect to the bottom of it? YouTube - Picture

So I Went to test my resistance on my MAF sensor and it isnt picking anything up. So does this sound like it could be the problem?

If you can't get a reading on your MAF it might be bad. That would cause a world of issues such as the one you are discribing but usually the car won't even rev up

my 2g had the same problem for some time last winter..it would take two or three cranks to get it started in cold and hesitates when i was on the throttle at idle..turns out my CTS connector came off. slide the sensor back in and BAM!

 

[panamarojo]

Well scratch the MAF, I measured the resistance on the actual sensor, but I re checked it and it is reading now. So I took the PCV off and tried to rattle it and it doesnt, its sticking so im going to try and clean it. I dont think this would cause such a big problem would it?

 

[panamarojo]

I cleaned the positive crankcase venilation and the car started up quicker and ran a little better but I am going to drive it to my other place cause I have moved and ill let yall know if there is any improvement. Also going to pressurize the waste gate to see if it opens. Also going to check the purge control valve today.
