-brief- i have a d16z6 in my 91 ef...running about 2 weeks ago...no CEL...
tranny went up so i pulled the motor...put new tranny and parts on plugged harness in and put back into car...plugged everything in...all fluids...

FIRST START UP- it idles fine at about 1,000rpm , when you go to rev it up...it bogs and wont go past 1,500

FIRST QUESTION-my fuel pressure gauge is at 20psi while car idles, on rev up it jumps around from 40 to 0????

SECOND QUESTION-my vafc 1...at idle "prs" (???what is that???) is in the -400"s, when reving it jumps to around from -300 -200 -100 ?????

MY PROBLEM I THINK - <U>wiring hack job </U>- someone did before i bought the car-

heres a picture the day i pulled it out ...harness untouched and still plugged in...

TPS ??? the grey sensor on back on Thorttle body, i guess the tps has 3 wires coming out of it...

#1 the red wire comes out and is cut ( as shown in black cirle TOP RIGHT)

#2 + 3- run straight over to the yellow plug on left side of intake manifold

SENSOR RUNNING TO ANOTHER SENSOR???? no wires go into harness????

PICTURE-




you can see the wires running back and forth to each other????

HELPPPPPPPPPPPPPPPPPPPPPPPPPPPP!!!!!

HERES A PICTURE OF CUT WIRES IN THE BACK OF MY HARNESS




COULD THIS HAVE AFFECT ON MY CAR NOT REVING AND BOGGING?

DOES TPS CONTROL THAT?

GAS???

VAFC?

HELP PLEASE

 

bump for answeres

 

I was having the same problem. Check your distibutor. I took my cap off and it looked like a brill-o pad. All the copper wire from the coil was everywhere. Only 2 cylinders were getting enough spark.

 

mine was just doing the same thing it was the dizzy

 

BUMP

thanks alot of the answers


the problem is BRAND NEW DISTRIBUTOR

i just got the obd1 conversion harness, p28 and brand new out of box distributor put on by tsr performance....

QUESTION- i had the wrong firing order on first start? did that mess up distributor?

 

help

 

take off your down pipe, and try reving with it off... could be a clogged cat???

 

problem fixed

as shown above in the pictures how the " tps grey sensor on back of TB " and the " clean sensor on left hand side of intake manifold " the iacv? whatever those two are...

they ran together before and not into the harness well i color matched some wires together and it worked..

im an idiot
