[QUOTE="Darryl L, post: 119257, member: 3734"] The TPS on the 1990 L98 is fixed and does not require .54v setting like the 89 and older ones. Leaking injector may be a possibility. I may just replace them due to their age at any rate. Possibly upgrade them a bit to suit the engine build specs. It' Now running a LT1 cam with 1.6 rockers, custom ported heads with 10.5-1 pistons. I still have a few ideas up my sleeve. It' winter here and its hard to have to heat the shop up to tinker so I've been doing work on the warmer days to save energy lol. [/QUOTE]
