Fuel, Emission, ? Problem

[akkordlayinkit]

Well the last day of driving the F22A1 I had a real bad problem with the car studdering upon acceleration...I figured it might be something to do with the A1 ignition.

I swap it with the F22B...and it runs great for the first 4-5 days, then the problem started again. Basically everything ignition wise is new, new fuel filter and such.

Heres what it does...when accelerating the engine studders like if it is getting no fuel...it'll do that at random times. Also it has a new thing it likes to do-when Im driving steady keeping the RPMs and speed steady, the speedo will be acting crazy...the needle will be jumping up and down very fast. It also backfires quite a bit when its doing its studdering phase.

Im thinking it might be something fuel related, maybe fuel pump?My buddy said it could be emissions-since I keep the EGR from the F22B? I thought it might be something ignition wise, but everything is new. Could it be the main relay, fuel pump?

well you said you had this problem with thea1 right? and now your having the problem with your new engine. and if its the same problem on different engines it has to be your egr ports/vavle because you swapped that over from the a1 right. if iwas you i would of cleaned the egr ports while u had the intake mani off. but you can still do it by removing the access pluggs. theres plenty of info on here including a diy. i would do this. when i had my egr ports clogged acceleration was very sluggish . ihave a 5 speed and first gear was reall bad and shaky. if you have this problem than i would clean your egr ports really well. this may not be your problem but sounds like the same problem i had. if you need more info for cleaning them pm me and ill give your the step by step and tools/pruducts needed.

I never took the intake manni off...I also cleaned the EGR valve so I really dont think its an emission problem.

I still think its a fuel problem but havent found the culprit yet.

Any more suggestions?

cleaning the egr valvewont do much. its the ports you have to clean. theres 6 of them and if u never have cleaned them then i guarantee some of them are clogged. if your egr valve is working properly u dont have toworry about that but u shouldclean your 6 ports. and no if there clogged you wont throw a code. sometimes u will throw a code and sometimes u wont. and u said u had this problem with the a1 did u not? did u clean the egr ports on the f22b? if not do it because its nothard just time consuming. u will be surprised what cleaning those 6 ports will do for your perfromance,studdering,acceleration etc.

for the speedo did u check your speed sensor? and have u checked your fuel injectors for the studdering problem? are they new/used injectors? hows your fuel filter? have u checked your fuel pump relay?

I checked the fuel main relay-it clicks...

I barely heard the fuel pump come on...?

What else can I check?

maybe it is your fuel pump. try replacing it? can u drive the car anywear at all?

Guess I should follow this up since the problem has been fixed for a little while...

Fuel pump was crapping out...got that straightened out...then I had no spark. Got to looking, and the wire on the ignitor that I ran to convert the F22B to External coil, was loose. So now its going good again.
