i had the ecu replaced,reprogrammed to my key,and it starts just fine. however im still experiencing the same symptoms with the d4 light flashing and the check engine light.my question is could it be 1 or more of the selonoids on the transmission? and what causes the misfire in the cylnders? wires,dist. cap,rotor button? or somthing else? i just had the timing belt, water pump, and the seals behind the cover replaced all with new belts.

 

Stop by a parts store and have your codes scanned. Post the codes on here.

 

i stopped by the parts store & got the codes:
P0758
P0300
P0301
P303
P304
P1399

let me know what you think,i sure will appreciate it cause i'm at a "brickwall"

 

You've got a miss fire on multi cyl's....tune up items? Starting simple with this question.

The 0758 is for the trans solenoid, be sure the connector is seated.

Also, this is the motor and trans out of an 02 installed in the 98...correct?

 

yes,thats correct. i'll take care of the tune up issues and see thr result. i'll check the connection also,are those the ones on top and mid-side?

 

Sorry, best pic I got, a bit of an eye chart. Shift B is #28 in the pic.

 

gotcha,as soon as the weather breaks(its storming here)i'm going to check it out,thanks.

 

Got you message, figured I can post the pic's here better.

One pic shows the testing of the solenoid...note which on goes to the POS + and which goes to the NEG -...then the first page of the testing for the P0758 shows which pin is which.

 

thanks,going to attempt to test it soon,my next step, if this isnt my solution,will the transmission shop.
