I pulled the o2 sensor and it runs so it must be a clogged cat. You were right on Old Man.

Run it long enough for the computer to set a code.

Thanks for the replies.I will try both ideas.

91 4.0 aw4 This is my son's truck but I try to keep it running for him. The darn thing starts but goes to 2500 rpm max and spits and sputters. I retrieved code 23 and 51 and looked them up. (MAT and o2 sensors) I pulled the ECM fuse and cleared the codes. I wanted to drive it to see if it set...

Get them erased and drive it a little more.

Did Autozone erase the codes for you? If so I would drive it some more to see if it happens again. 132 is o2 sensor.

Are you reading codes with an OBDII reader? what are the numbers?

for 96 and later it is no longer on the fuel rail

Look at Trouble starting must floor it? on here. Similar to your problem. On 96 the FPR is part of the fuel pump in the tank and really expensive.

I thought OBDII started in 96

do a search on crank position sensor (CPS) lots of info on here

do a search, there have been several recent threads on this

I know the 86's with 5 speeds had 4:10's according to the 86 sales brochure.

If you can, go to Autozone and have them read the OBDII codes. They are more definative as there may be more than one P code to go with your 33.
