Yea that's normal there's a mix of vehicles that got obd1 plugs but are obd2 emissions equipped a lot of Chevys are this way from95 to 96 year changes this happened a lot

Takes a obd1 scanner plug but is actually obd2 system .i had to buy an adapter for my scanner

 

Oooh ok yea I've driven the truck around for a while to see it would go away but nothing. It hasn't act up again ill keep trying on resetting that cel.

 

It's proably not going to reset if the open fault wiring code is stil present if its running good then I wouldn't be to worried but there's always that emission test ... May require further digging to get it to go away might check ecu connections for any corrosion at the connections if you have already checked the o2 harness and it has checked out

 

So how did you know you had a code? Did the check engine light come on? Or were you just testing to see if it had codes on it?

 

Light came on, so I jumped at the diagnosis

 

I did notice this, that no matter how hot its outside like that last time it was 103º my temp gauge never even hit mid ways it stays close to the C (cool). Hhhhhhmm

 

How about the MAF?

 

If there's no code for it , it's probably functioning right they can be cleaned though gently with Maf air cleaner or some q tips if you can get to the sensing bulbs to wipe them off

 

Do I use a cleaner or alcohol or something? Thanx!!!!

 

They make a mas air cleaner in a aerosol can ..but I've always been old school or garage style and grab a few q-tips and and clean the sensing bulb ... U can add some sort of cleaner if you wish but usually a few swipes will get it clean ......

Side note I did a have bud with a celiac gts and a kn filter his was so gummed up with filter oil it killed his throttle response to the point the car couldn't pull in front of traffic .. . A few swipes from the q-tips it was back to grabbing gears

My truck sound and acts like this guys truck, when it's been driven for a while. Thanx ill try that.

 

Watched the vid so your truck is dying out sluggish gas pedal un responsive . .. Have seen some Maf cars do that delayed throttle response .. And not set a check engine light ...or overall sluggish feel when driving .., try cleaning it before you spend any cash. As Maf aren't t cheap

 

Will do thanx

 

Can this be cleaned?

 

How about this?

 

Have you checked your fuel filter? also EFI relay?
Also check your battery voltage as well voltage while truck is running.
It's been about a month. Have you figured out what the issue was?

 

Normally I don't go spraying electronic cleaner in my dizzy . But if your willing it can be done
The Maf door in that other pick wich that is what it looks like ....can see some blackish dirt around the edges of the door prop it open with your finger or a wedge and spray maf cleaner in there if you want . But the sensing bulb is we're you'll want to clean the most

 

The top picture is the top part of the maf,
And no I'm still working on making it run fine.

 

Yea I ment I wouldn't spray electronic cleaner in there as I don't do that on my own distributer my only
Electronic part ....I'd try cleaning the Maf and did you ever mess with the coolant temp sensor or test its ohm reading ..not sure on the range of ohms it's function in tho

 

Ooohh ok, no I haven't checked the sensor yet. Its on my to do list.
