a few weeks ago my civic started to stall mostly when trying to pull out into traffic... I put my foot down to probally half or so throttle and the bips forward a bit then acts like its idling... i have to back off the ease into it a few times then it will take off like everything is fine. It doesnt really do it after i get going though. If it does, it will be when trying to pass and even then it with just kinna hickup a time or to and go.

I just changed plugs, wires, dizzy cap and rotor, and the fuel filter last year (about 10k ish miles ago) I checked the plugs the other day and they look fine, they were gaped a little far, im guessing just from wear, so i re gapped them and reinstalled.

The only thing that has changed is that, just before this started, i was in a minor accident. Someone backed into me but it wasnt really enough to do much damage. Just the hood and bumper and a slight kink in the core support. So i think thats just a coincident.... or my car is pissed at me >.>

Any CEL codes?

Ignition timing set to spec with a timing gun?

Have you voltage tested the TPS?

Is the FPR working properly?

vartok

no CEL and yes it works

I dont have a timing gun and have never used one

I seem to have lost my hanes manual, whats the proper testing prosedure on the TPS and FPR? i didnt see them in the FAQs

You may be able to rent a timing gun at an auto parts store. There's a diagram for adjusting the ignition timing in the FAQs sticky.

Testing the FPR is done while measuring the fuel pressure, for which a diagram can be found in the FAQs sticky.

The TPS has 3 wires, power, ground, output to ECU. Verify that the TPS receives 5 reference volts from the ECU, and outputs about 0.5V at closed idle and about 4.5V at WOT. There should also be a smooth voltage transition from closed to WOT.

vartok

TPS:
5.01v from ecu
0.49v @ idle
4.45v @ WOT

It looked to change smoothly, but Im using a cheap $15 multi-meter from walmart


I guess ill see if i can pick up a timing gun and fuel pressue guage from oreilly's tomorrow (only autoparts store around without having to drive 25 miles)

vartok

picked up a timing light today, may go out there and check timing tonight, might not... its awfully cold

I when to all the auto parts places and no one has a pressure gauge that will work on that banjo bolt... well autozone had one to "rent" for $200, but i dont have that much cash just laying around. Any suggestions? i remember seeing someone say something about just a little gauge that replaces that bolt and you leave it on there... know where i can get one of those?

vartok

had to take it to a shop to test fuel pressure.... 34psi while running and right after it stalles
it spikes to 45psi (loss of vac pressure), so it looks liek the fuel system is fine...

I tryed to read timing last night but i cant make heads or tails of it... that and the color on the marks are gone

Former User

The timing marks on the crank pulley are organized like this:

.....................l l l..................... l.............................

With the service connector jumped and the warm engine idling, the pointer on the lower timing belt cover should align with the middle mark in the group of three.

vartok

Which pointer, the v cut tab or the little pointer a bit lower?

Former User

Both. It works like a gun sight.

vartok

ok, set the timing as best i can... it looks correct to me. But it still stalls out... i made a short video here :

Broke down about a mile from home.... I was able to limp to a autoparts store where a friend works.... At that point it stoped getting spark.... Replaced the cap and rotor just to make sure.... Fired right up an no stalling... I feel dumb now... I didn't think about replacing it again after a year
