Update ,

checked continuity between pin 50 , 9  and maf connector is .0-.2ohm . Between maf connector and ground .0 , and KOEO I got 11.7V .

I back probed at the maf the signal return and on a wide open I bearly hit 3.02V , same as my quaterhorse read on a log.

Hello ,

Where is the diagram for the Test #1 in the trouble shooting procedure ?   

Stock 91 A9P here , code 66 only.  On a mid-hard acceleration , engine is bugging a lot , Maf voltage will not  go over 2.x volt. , on a free rev it will raise without bugging.

Changed three capacitor because they had leaked.

Tested another sensor, and connection , all the same issue .

That car is bone stock.  when I unplug the maf , it will pull like a stock 91 , when plugged like a old Tempo 4 banger.

Hi All
been a while for me! Is there anyone still out there? Hope your all well and playing safe.
Simple question I have a 1970 Torino Thunderjet 429.
Engine misses on 1 and 6. Directly opposite on the distributor and running same port on the Edelbrock Performer RPM.
Tried caps, rotors, different leads and distributor.
No vacuum leaks I can find, good compression on both, cam lifts about right with dial indicator on the rocker arms. New plugs.
770 vac sec Holley new power valve etc etc. WTF am I missing?
Regards
Stephen

Hey guy's, I recently found out I have a blown head gasket  the motor specs are as follows:
New Style Boss Blocked 331 Stroker. Vic JR Loc Wire Heads W/1/2" Head Studs, Vic JR Intake,
D-1SC Procharger @ 12LB Boost and about 500 miles on motor. Compression check was good.

My question is what is your opinion on using.....  Blue Devil Head Sealer to fix the problem?
I do not know if it is more critical as the motor is forced induction.
I do realize this is not the correct method to fix this problem but I would like to know what everyone thinks. thanks, James.
