I HAVE A BIG PROBLEM. I OWN 1 1ST GEN. IT HAS A FULLY WORKED 12 A. WERE TALKING STREET PORT, HOLLEY 650, HIGH PRESSURE HOLLEY FUEL PUMP, UPGRADED FUEL PRESSURE REGULATOR, HIGH COMPRESSION ROTORS, LOW COMPRESSION CARBON APEX SEALS,2 MSD IGNITION MODULES WITH BLASTER COILS, HEADERS,FULL STRAIGHT PIPE EXHAUST, LIGHT WEIGHT FLYWHEEL,ETC.. I GUESS THATS ENOUGH INFO TO TRY AND FIND OUT THE ISSUE. NOW THE PROBLEM, MY MECHANIC TUNED THE CARB, AND ADJUSTED THE F.P.R., REWIRED MY MSD, ADJUSTED THE TIMING, AND CHANGED MY SPARK PLUGS. ONE OF MY COILS IS NOT RECIEVING SPARK, THEN WE SWITCHED THE COILS AND IT WORKED BUT THEN STOPPED. THEN WE PUT THE OLD ONE BACK AND IT WORKED AND ALSO THEN STOPPED. THE CAR TURNS ON LIKE A CHAMP, JUST LIKE IF IT WAS FUEL INJECTED. IT IDLES BEAUTIFULLY!!! BUT THE SECOND WE GO TO GIVE IT GAS IT SPUTTERS VIOLENTLY! IT SHAKES SO HARD THAT MY SHIFTER INSIDE LOOKS LIKE ITS GOING TO JUMP OUT OF THE CAR AS WELL AS THE MOTOR DOES. EVERYTHING ON THE CAR IS A PERFORMANCE PART. THE MOTOR HAS 10K ON IT. THE CAR WAS COMPLETLEY PUT TOGETHER FROM THE FRAME UP. WE HAVE NO IDEA WHAT IT COULD BE. IF ANYONE HAS ANY FEEDBACK PLEASE LET ME KNOW HERE ON THE FROUM OR BY EMAIL. FRANCISCO.A.FERNANDEZ@GMAIL.COM

THANK YOU VERY MUCH.......

 

why does the coil only work at idle? its either bad or its not wired up right

 

so this started after your mechanic rewired it? how about re-rewiring to how it was before it was rewired.

 

the coils are on and off. they both work and both dont work, sometimes they both fire, somethimes only one. its like they take turns firing. i bought new ones and still the same issue.

 

this was like this before my mechanic touched it. he just changed the wiring and butt connectors because the old ones were old and worn out. he even returned it back to stock set-up with no msd and it still acts up.

 

well the present diagnosis is, blown rear apex seal... that sucks. now im left with these options, sell the car as is and try to get as much possible, fix my motor, put in a 12a with street port and half bridge that my boy is selling me or just go 13b turbo, decisions, decisions......

 

im going to post some videos of my car so everyone can see the issues im having with the car...

 

well about that problem, we said the hell with it and just put another 12a in. mine was shot. so we got a street ported half bridged and put it in.....nice, and to think some say hes not a mechanic

 

Thanks for letting me know. I was waiting around today for you to stop by.

 

.....and most guys find it easier to remove/install a motor if you remove the hood!
