HELLO EVERYONE!!I HAVE BUILT A VERY STOUT L98 DONATED FROM A 1985 LOW MILAGE TPI VETT.I HAVE A 52MM EDLEBROCK T.B AND 24LBS ACELL INJECTORS.I HAVE DONE SOME HEAVY PORT AND POLISH WORK TO THE TPI,INTAKE AND CYLINDER HEADS.IT'S ALL BREATHING THROUGH EDLEBROCK HEADERS, CLEANED CAT AND THREE INCH FLOW MASTER PIPE AND CAN.I INSTALLED A MODEST CAM KNOWING THAT THE TPI CAN ONLY DELIVER TO 5600-5800 RPM!I'VE ALSO HAD A CUSTOM PROM PROGRAMED FROM JET CHIPS{WITH AN ENGENEERING SHEET}

THIS ENGINE REPLACED THE STOCK 5.0 TPI MILL.

SINCE MY ENGINE SWAP THE NEW MILL HAS BEEN RUNNING RICH AND I'M GETTING INTERMITTEN SES CODES 21,33{THESE CODES COME AND GO AT WILL}.I'M WOUNDERING WHAT ARE SOME POSSIBLE SOLUTIONS?I'VE ALREADY SET MY MINIMUM AIR AND TPS I ALSO MADE SURE TO USE ALL THE 5.0L SENSORS.I HAVE REMOVED THE STOCK AIR BOX AND INSTALLED A CONE K&N ON THE END OF THE MAF.IS THIS A MISTAKE?. THE CAR WHEN IT SETS THE SES LIGHT WHILE DRIVEING WILL STUDDER FOR SPLIT SECOND THEN PICK BACK UP ON DEFAULT ECM SETTINGS.

I AM COMPLETELY CONFUSED!!!!!{FRUSTERATED}
P.S IT WORKS LIKE THE RING TAILS OF HELL WHEN THE SES LIGHT STAYS OFF!!!!!!!!!

Kill the CAPS LOCK, it makes your posts extremely difficult to read, and comes across as if you are SCREAMING AT EVERYONE.

 

gotcha !

 

I was thinking the SAME thing.....

 

Check out www.compcams.com

Go to the online catalog and check out the extreme energy cams for pre 86 blocks. Look for the one with the rpm range you want.

I have XEH262-10 and it makes around 310 hp and 375 lbs tq.

Depending on your heads and intake mods you could be making a bit more horsepower with a good 40 more lbs tq.
