Haven't been here in a while. My car is a 94 with 225k miles on it. The longblock, injectors, throttle body, wiring, distributor, and most sensors are all stock.
The coil has about 100k miles on it.
About 2 months ago the car noticably lost power at the top end and started hesitating when going from cruisng to accelerating. This started to get worse so I changed plugs/wires/cap/rotor. This made a slight difference.
The problem continued to get worse and I developed an exhaust leak (header to x-pipe). I fixed the exhaust leak, treated the gas with fuesl system cleaner a couple times, changed the fuel filter, and seafoamed the intake. The problem is still there and keeps getting worse.
Last night I pulled the SPOUT and the car stumbled and backfired horribly.
I have a TWEECer RT but I am not proficcinet with it. What can I datalog or watch to try and determine what has failed. I am not sure if it is an injector / distributor (PIP) / ignition module / etc.
Thoughts????
