hey everyone this is my first post, unfortunately, it's me asking for help on an issue I've been stumped on lol. I have a ka24e 240sx and the car was running perfectly fine with no issues for a few months since I got it.

My problem is it runs really bad at idle. This all started after I took off my valve cover gasket to paint it, after painting it I put it back on and the car started having issues. (I know I was bored during the covid lockdown and had nothing better to do lol) When I start the car, it stays around 500rpm and after a few seconds, it'll just die. If I have my foot on the throttle it's fine but does smell like gas and I do hear some pops and the end of the exhaust but the second I let off the gas it dies again. The engine does also shake when starting and running.

I've talked to several people and many of them not being sure if it's a fuel issue or a vacuum leak somewhere. Some of the stuff I've tried is cleaning out the MAF and the whole intake setup, new fuel injectors, and a new valve cover gasket.

Below is a video I took of it 馃榿

Sounds like the FPR has died. See if pulling the line off the top changes anything or even if fuel comes out.

Now would be a good time for a Tune up if you haven't done one yet. Fuel Filter, Plugs, Wires, Cap & Rotor to start.

I have a 95 hardbody with the same issue. Timing is right all the way around. New fuel pump, filter, and injectors helped a little. A drive down the street and the headers glow. No power. Won鈥檛 go past 30 mph. FPR is next. Oh and it鈥檚 throwing 1 code鈥 code 55 which is NO MALFUNCTION
