okay, i just replaced the EGR valve and i still have this stuttering/stalling problem whenever i reach a certain rpm (i dont have a tach, so i wouldnt know exact). I cannot press more than 15% of the gas otherwise it will start sputtering.

so far, we replaced the fuel pump, fuel filter, plugs, egr valve, oil/oil filter are recent. (88 camry, 165k, automatic)

The car kinda putters with the new egr valve, kinda like a lawnmower. possible problems would be distributor, o2 sensor?, or a fuel injector problem. whenever i rev it in park, it usually can go a bit higher than in drive.

i have a sound link of the car (its actually in .wmv format becuz thats the only thing i can host, there is no picture beuz it was at night, lol) also, that rattling noise is the strut bar hitting the hood, dont worry about it ;)

here it is...

ive searched in the past and my conclusion came down to the egr valve..now that ive replaced it, i pretty much ran out of ideas.

That's about the worst sounding Camry I've ever heard... I hope you have open exhaust or something...

The symptoms you describe point to an ignition system problem. Check your timing, spark plugs, wires/cap, rotor and ignition coil.

The way it sounds makes me think the motor is blown... you might also want to check your coolant for oil, your oil for coolant and do a compression check.

Good luck finding the problem!

i know! it sounds soooo bad.

it does have an exhaust leak on it. problem is...we've kinda already dumped hella money into it already.
160 for a egr valve is a lot considering the egr valve didnt fix the problem, lol.

If it's the 4 cylinder 3SFE engine, check the coil inside the distributor. They are a known problem on this engine. You will need a digital volt/ohmeter and a Chilton's or Hayne's manual for this, unless you can see a visual crack on it. You can get an aftermarket one for around $40-$50. No need to replace the whole distributor as a Toyota dealer would recommend.

alrite, we already have a spare distributor that we bought but never thought it woulkd be the distributor, maybe we should just replace it and see.

As a general rule on old Toyotas - always check the ignition system first before replacing other parts.

wed3k,

Sorry, I didn't notice before that you didn't change out the plug wires, just the plugs. Before taking the distributor out of the car, take the distriibutor cap off (you will have to do that anyway to remove the distributor) and check the plug wires through the cap with a DVM for resistance. Check from the terminal inside the cap out to the other end of the wire (the end normally attached to the plug). A good rule of thumb is 7,000 OHMs per foot. Don't be surprised if you find 1 or 2 open circuits. The wires on this engine are noted for breaking down internally, leaving you with an open circuit. Under light throttle the spark can jump the open gap inside the wire and eventually reach the plugs to fire them. Under heavier excelleration a stronger spark is needed and the wires just can't handle the current, causing a missfire. Checking with the DVM before removing the whole distributor should take about 5 minutes. If you find any open wires, this is most likely your problem. The cap and wires on this engine must be replaced as a unit.

Good luck with the problem.

that is making sense, my friend and i are going to replace the distributor and check the timing 2morrow. we might just repalce the wires as well.

OH! and i also remembered that there is an extra hole on that EGR valve. i didnt plug it up when i ran that video/sound file...today i got a bolt, plugged it up and now it sounds normal at idle...it doesnt want to die as bad but still stutters.

HOLY JESUS!!!

replaced the distributor and wires and the thing actually runs!!! i can floor it down the street and it wont stutter at all.

i checked the timing first, it was normal (10), pulled the plug (Bosch Plantinum 4's) it was a black in color, no oil or grody shit on it though, then changed the distributor.

it was really easy, swapped it in and out...adjusted the timing and only took us like 2-3 hours. this was becuz i was talking to my friend and he was showing off with his sound system and whatnot...

but my dad told me that the wires DID fail in 2001, so the wires do break down internally. Anyways, thanks for the help guys!
