jerky acceleration
97 prelude base
AEM intake, greddy exhaust
I get jerky acceleration/loss of power every once in a while, seems to happen only on a cold engine/cooler days. Almost a choking/struggling feeling. Only happens for a minute or 2 after startup. Any ideas? EGR?

i would do that and spark plugs/wires. Might as well change the oil and oil filter along with a distributor cap and rotor.
that just me tho. Would rather change it all now and know everything is new.

I was going to replace the fuel filter for my 97 base as well as I was getting something similar occasionally, but I was told that Fram filters suck and I should stick with the OEM parts. Is there a difference?

Re: jerky acceleration (tuffghst)
bumping this back up.
I replaced the air filter, fuel filter, plugs, wires, distrib cap/rotor...all with top quality stuff.
Still seem to have the same problem. Temp doesn't seem to matter as i originally thought and it happens out of vtec. Still get a choking/struggling feeling that lasts sometimes a couple seconds and sometimes a minute or 2. Not sure what my next step should be.

Re: jerky acceleration (prelude_93vtec)
does it happen between 2500 and 3k revs? if so it might be the EGR or EGR manifold that is blocked a bit. that is what was wrong with my 97. had it cleaned out and prob gone.

Re: jerky acceleration (KAZZ_786)
its manual.
it does seem to happen at lower rpms...after the initial struggling it will then "launch" or lurch/kick ahead to normal acceleration. I've read up on EGR and it seems to have the right symptoms.

Re: (tuffghst)
My car is a 92 vtec and it feels very choky at times too. I believe the stock exhaust has some kinda restriction. Can't wait to change it. Is your exhaust stock as well?
