2.3L Problems.

akatagyourit · June 6th, 2007, 08:51 PM

Ok so heres my problem folks. Rebuilt a 2.3L engine had a higher performance cam put in, port and polished the head, new header, and some other random stuff. I'm slowly replacing stuff as needed to try and fix my current problem and was hoping someone here might be able to help me. When I go out in the morning and start my car it starts fine and runs fine for the most part. Now once I start driving it and get it to tac 4k rpms the car starts having a miss. Through all rpms and all gears till the engine warms up and eventually the miss goes away and doesn't show back up. I replaced the ignition coil, spark plug wires, and spark plugs thinking it was somewhere in there. So anyone experience or know what might be causing it?

Edited - 1987 2.3L engine. 1988 Body.

well i really dont kno too much about the actual mechanics of the engine but if u adjust ur timing and take the knock sensor off it might help

akatagyourit · June 6th, 2007, 09:17 PM

Timing has been set as best as it can be. When the miss isn't happening the car runs fantastic its just the initial startup and reaching 4k rpms.

akatagyourit · June 6th, 2007, 09:17 PM

As for the knock sensor wtf is that and where is it?

TurboLX · June 7th, 2007, 12:51 AM

the cylinder mite be MISS-Firing, problably because the valves arent opening properly or are staying shut some times

How would I go about testing this and/or fixing this if it is the problem?

TurboLX · June 7th, 2007, 04:29 PM

what kind of cam do you have? whats the lift and has it been properly broken in?

akatagyourit · June 7th, 2007, 09:26 PM

The specs and such will be posted soon as I get a 100% answer on what cam it is. Effin mechanic won't give me the info for some effin reason so I'll post it soon as I can.

TurboLX · June 7th, 2007, 09:26 PM

ok then

akatagyourit · June 24th, 2007, 12:31 PM

Ok well after long delay heres the cam Specs.

Its a Speed Pro CS1156R Hydraulic Camshaft.

Ford 2.3L Hydraulic camshaft, 1500-5000 rpm range, adv. duration 282 intake/ 282 exhaust, duration @ .050 of 220 intake and 220 exhaust, valve lift of .454 intake and .454 exhaust, Lobe C/L is 112.

Thats from summit and here is what we were told it was.

Camlift Int. 270 Ex. 270
Valvelift Int. 454 Ex. 454
Duration @ .050 lift 220/220
@ .050 lift 282/282
Lobe C/L 112
Overlap 45

So lets try to get the pony running correctly.

MSO · June 24th, 2007, 12:36 PM

so its basically a stage 2 cam?

rough idle, power in the 3500-6200 with those specs

or am i thinking of something else?

akatagyourit · June 24th, 2007, 12:56 PM

It idles fine in its current state. It just that god forsaken misses that pisses me off that i'm trying to fix. As for power it picks up about 2-2500 rpms. Redline on the car is about 5500 rpms if I recall correctly. Dunno never wound the car up past 5000. Regardless cold start tack 4000 rpms and a hard miss comes into play and stays there till the engine warms up. TurboLX was saying the valves aren't opening properly or staying shut some times which could be causing it. He asked for the cam specs so here they are. Hopefully this will give enough info to try and get this car purring instead of gagging and puking.

Edited - Forgot the major changes to this engine are the cam, port and polish and the head was shaved like .080 of an inch or something close to that.

TurboLX · June 24th, 2007, 01:08 PM

well the specs of the cam do kinda help if you posted them

MSO · June 24th, 2007, 01:10 PM

well, all 2.3s pick up power at 2-2500 cuz the torque peak is 2400 rpms lol

and it lasts until 5k cuz thats where the hp peak is lol

well, did u get valves with the cam swap? i wud've definitely done that if i got that cam

Yes the head was sent to the shop to have new springs, retainers and everything installed properly with the new cam.
