Miss hesitation

[ozzy smith]

so I'm back I still can't figure out the problem . I have a miss hesitation problem no cel tho and no codes come out. I replaced dis module nothing changed . Spark plug . Wires and also cam sensor.and coil pack . I was wondering if anybody has ever had this problem I've read a situation like this and it was the crank sensor. Can that cause a miss or lost in performance? Sometimes car does not start right up.

Also I forgot to say I disconnected the maf and it runs better with out it for like 2 days then runs bad again

What's your fuel pressure?

 

[ozzy smith]

Honestly I haven't tested but it is running rich tho and my gas mileage sucks

I had no codes on my previous 95 MTX and the fuel pressure regulator failed. It was up at 80psi and I had no codes, but a constant stumble around 2000 to 2500 RPM. Putting in a new regulator helped some, but it also needed plug wires to get it running better. Check the pressure at the Schrader valve

Sometimes car does not start right up.

Try disconnecting the cam sensor wiring and see if things improve. There is usually a code for the cam sensor, but it is worth trying.

 

[ozzy smith]

I've tried that it with the cam sensor disconnected it also runs better I just hate the hard starts

 

[ozzy smith]

Cam sensor is new

 

[ozzy smith]

And my problem is like all rpm just like a bad ignition problem

 

[zoomlater]

Unplugging the cam sensor can result in multiple tries to start the car. Does the car run fine with it unplugged or does it still miss.

 

[ozzy smith]

It still has a miss . But not as worse you see if I disconnected it runs better. But still misses. If I disconnect the maf or runs better but still has a miss. What is the function of the crank position? Not just to start but as the car is on?

So on what I've read I guess the cam and crank position sensor have similar symptoms? Also I replaced my cam sensor twice just for the heck of it one from orallys and the other one from auto zone. Also now that I remember previous events that happen with the car it turn off on me every time I would let go off the gas that was right after I did the crank seal but it just went away then that same thing happen again but 4months later so idk if does are signs maybe

when you have the cam sensor disconnected, is the miss random or consistent? (can you narrow it down to one cylinder, or is it random on any?)

 

[ozzy smith]

When it's disconnected it seems like it's all I mean it has no power what so ever .consistent

 

[ozzy smith]

So guys replaced the crank position sensor car ran better I felt it. But didn't fix the problem but did run better. I also had a dis module that I bought from Sho source swap it off it ran a whole lot better. But still misses here and their I'm out of ideas spark plug good wires good cool good cam sensor good and crank good and did replaced what can cause a miss then and of course no cel

 

[zoomlater]

Did you check your fuel pressure

 

[ozzy smith]

No . I don't have a gauge.

 

[ozzy smith]

But I do press on the regulator and it comes out

 

[zoomlater]

Did you try pressing the Schrader valve, if the gas shoots out, then you maybe okay. You could try and call an auto store to see if they have a gage your can borrow
