So I recently have developed a problem where my car would not want to idle very well and started bogging down and gets horrible fuel economy when driving, about 14mpg. I stored my car for the first time back in Dec 2017 and before then it was in AZ so it was regularly driven and never stored. I pulled it out of storage in May 2018, with occasional starts every month and added Stabil. I've added fresh gas since then, whole tank of 93 oct.
I adjusted the timing and got it close to where it needs to be, but I've got a Fidanza flywheel which doesn't have clear markings for the 15deg TDC, so I tried to match it up to the one tick mark I see on there with the timing light.
Symptoms:
-bad gas mileage, 14mpg
-stumbling when cruising on highway, randomly feels like throttle is closing/opening while my foot is steady, sort of feels like its missing too
-no power until I'm past 4-5k rpm and even then doesn't feel like its 100% at WOT. When I try and accel from 2-3k rpm it sometimes bogs down and goes nowhere
-no CEL or anything on the cluster
I have a 70mm BLOX throttle body and TPS sensor bolted to a Skunk2 IM running Type S camshafts and an RMF header with an Apexi WS2 catback.
Back in 2014 it put down 191whp, but it feels like its only making 100hp or less now at certain times.
Even though I don't have a CEL, should I consider replacing the TPS or do you think it could be related to a clogged/plugged Cat?
Spark plugs and NGK wires were done 6k miles ago along with intake/exhaust valve stem seals so it doesn't smoke at all, and its got a brand new Distributor (cap, rotor, coil, ignitor....entire unit)
