Hesitates and cut out randomly

[Chatmanboy]

Been having a problem i cant figure out the past few days.

My car hesitates and SES light flickers, the car cuts off sometimes when i come to a stop. But starts back up. Wondering what should i check? Could it be electrical?

I checked the MAF its seem good, what else could cause this?

Flickering of the ce light sounds like a problem with the chip, ecm or ecm connection. Is this a T top car? They are notorious for leaking water on the ecm. Check the ecm plugs for corrosion. Pull the chip, clean socket if necessary. Use a pin or needle to bend the legs in the chip socket up to make better connection with chip.

No this isnt a t-top but will see if the ecm is the problem. we keep u informed. thanks

X2 on chip connection or low voltage output from alternator.

Check engine harness grounds, and crank sensor as well.

I checked and they all checked out good!? Then when i start the car the "Service engine soon" light flicker once then goes away. No code! While still in park i rev the engine and the light flickers again!?

these are the scanmaster readings

O2 777
AF 08
L8 52
BAT 13.1
INT 128
BL 128
MPH 0
CLT 160
ATS 54
r 850
TPS .44
IAC 72
cc 151
MAL 0

your mass airflow readings are a little high at 08,should be around 04 or 05 at idle with a TT chip.

would that cause it to do what its doing? i tried to get it to come down by adjusting the iac but didnt do anything. I also noticed a spark plug wire touching the manifold but burned a lil but wouldnt think it would cause the SES and hestitation to occur.

Think i found the problem, the wiring connection ign module to the crank sensor was lose. Going to test drive and see if that was the case. Appreciate the help

Hope that was it!!!

where can i find ign module to the crank sensor? having the same problem.

That's either the plug on the module under the coil packs.

Check your fuel pressure. Make sure regulator is doing it's job.

Something else is going on.
In my observation, the L8 number is on the high side.

With the TPS/rpm in check something is throwing this number off.
Yes, a MAF will throw it off, but not sure if would be this much.

The MAF reading should be around 6-7 at that rpm
If the IAC is set around 20, the MAF will probably come down.
