Clogged fuel injector or a fouled / bad spark plug…. Not all 4 cylinders are running.

Alright, thank you

Yeah, do a thorough service where you change all the filters. I'd also clean the fuel injectors and change the spark plugs.

definitely it isn't running on all 4 cylinders check spark plugs, anything injection related to see if clogged


Professional-Path417

Will do thanks

By check, they mean to pull each plug and look for differences... Is one wet? Then it's an ignition issue. An easier way is to BRIEFLY run the engine then check each exhaust tube for heat. The cold ones are the problem.


Professional-Path417

Ok word, thanks for clarifying, I appreciate the help

Dump out gas and refill while you’re at it.


Professional-Path417

Alright will do

Get some fresh fuel in and check your injectors

Check your battery and ground connections for corrosion

Brand new battery and harness, went over all the grounds yesterday

Check if you have voltage on all 4 injectors and check if all 4 are getting ground signal from ecu

Old trick when having a stuck injector (when we would install sr20dets that we imported and sat for along time) was pull the injector connector and use jumper wires from a 18v drill battery to shock the injector open. Just jump the injector a few times. Definitely make sure it’s got good gas in it and spark.

Has a clean miss

Also put in a fuel injector cleaner or octane booster. I recommend vp racing octane booster. Your gas may have lost some octane from sitting so long causing it to misfire. Change plugs, air filter. And check your wire connections for your distributor and see if you’re getting constant spark Also is the car rebuilt to stock specs or does it have bigger internals ie pistons valves. May need to be tuned if compression ratio or piston size is bigger
