Going down the road or sitting in the garage holding the throttle at about 1400 rpm or so, ( rpms dont mater) the engine cuts out (skips)
The analyzer shows codes 22 &34 , TPS & MAP replaced both and still does it. And still shows 22 &34. After clearing codes and running again.
Checked vacume lines found a couple spots that were rubbed thin but not thru put some tape on the spots to see if it were a possible leak no change.
I cant find a shrader valve to chack the fuel press. So how do I go about doing that?
Pulling my hair out at this point and the wife is pissed I havnt fixed her car yet!
With the key on check the voltage on all 3 wires @ the tps and map sensor let me know what thay are. Is this the 4 cyl or v6?

Check the voltage on the 3 wires

With the key on engine not running reading from each pin, meter grounded to alternator housing
blue & black wires read.01 volt set on 20volt on meter
grey wire read.00
A &B read.01 volt

Your missing the 5 volt refference signal on the to sensors. That gray wire must have 5 volts out of the pcm to the sensor

What are the chances it is both wires to the sensors as opposed to being the pcm bad?

Thay share the same 5 volts if its missing @ the computer check all your powers and grounds

I have another one of those cars I swapped computers, same problem.
So I tried moving the wire harness where it comes out of the fire wall while it was running and it smoothed out, so I guess I just have to figure out which wire and where it is bad.
And there is SOOO much room to work in there this is going to be fun.
