helllllppp my car runs like sh$^$
help

 

what ecu are u running? that may be your problem

 

have any codes on the ecu? could be a bad dist

 

im running a p28.............it runs great till it hits 3500 rpms idels great ...........no vaccum leaks, timing is great hot or hot or underload or not it still bounces off the rpms at 3500 almost like a rev limiter at 3500
any ideas
brent


keep the ideas coming

 

ok i took it down the road for another test drive 1st took it 3500 bounced off what feels like a rev limiter and it did this all the way till 5th gear

this swap is driving me nuts

you guys helping me

 

its on limp mode, u have something wrong in wiring or jumper, once u get that problem solved that will go away, but u need to figure out whats wrong....yuo should be throwing CEL's when ur on limp mode...so check for that...if you cant check them....ur going to have a fun time....

 

check your wiring harness but better just to get a new ecu

 

Check your timing. I had the same problem you are describing and wound up bending a valve. I repeat check you timing. If you are off a tooth then your car will only rev to 3500.

 

timing was adjusted to spec still throwing codes for o2 and crank angle not too worried bout o2 but crank angle not sure sounds like some $$$$


any ideas

 

So its not throwing any codes?CEL whatsoever?

Come on... atleast read the post's. I am not a expert on these swaps but I just read a post a while back that you were sopposed to run 2 wires to the crank angle sensor. Maybe from the Dizzy?

 

2 wires to the crank angle ?

 

Yuup... from what I understand: the stock Dizzy has that sensor in it. But with your hybrid... maybe that sensor is somewhere else...


Again, dont quote me on this... but I would try searching.

 

did you ever figure out why your car didn't rev more that 3500? i am having the same problem, and i can't figure out what to do, i have tried everything i can think of so any helpful advice would be much appreciated.

 

no its still doing it i e-mailed locash and they said my dizzy was wired wrong ??? well i hope so cause i tried like every combination they said go to the junk yard and get a hf or si harness side 7 wire plug for the dizzy and use the adapter they gave me to plug it into the obd1 dizzy

brent hope he is rite or im givin up gonna pay to get it done

 

your map sensor is unplugged

 

nope tried that too we think we wired the dx dizzy plug up wrong to the obd1 dizzy

using p28

 

i had the same problem , my problem was when i put the gas pedal to the floor it would bogg its a$$ off at 3500. to fix it u will have to swap the 2 outer tps wires and while you are at it just check the tps over to make sure it is not broken. if i am not mistaken that will fixx ur prob. hope i helped

 

problem still not solved posting some pics of the ride so hopefully it will ecourage some good ideas

i give up .........i really dont wanna pay someone to find out whats wrong

 

Sounds like a distributor problem.

Please list the colours of your STock harness and the harness on your distributor.

 

harnes--dizzy

peach ----------------white
white/blue------------white blue
c1 for mpfi-----------blue/yellow
thin white wire-------peach
peach/blue-----------peach blue
c2 for mpfi------------blue
fat white--------------yellow/green

this is how we have it hooked up now we tried to move around c1 and c2 and thin and thick white but nothing else
help thanks
