Missing

[jackfrost1031]

My camry is missing pretty badly at low RPM, particularly pulling out onto the road or from a parking space. It goes away somewhat after a little while, but still kinda bad in the <2k range.

I think maybe it's because it's sat for the better part of 6 months apart or being put to gether, and just needs to be driven more.

Would seafoam be a good idea?

I have brand new plug wires, replaced the plugs in the past few months, cap and rotor and a JY distributor.

I've checked vacuum lines, any other tips?

Seafoam will smooth it out a little bit if you add it in the oil, but I doubt it's going to fix the problem.
It sounds more like a vacuum leak to me.

Check the plug wires. Some of the aftermarket ones have a tuff time gripping the plugs & distributor. Make sure they're on nice and tight.
Recheck the timing. 10*btdc when you put the ECU into diagnostic mode.

It's either running or not. Running it more is not going to fix anything.

The fuel sitting in the tank could have degraded sitting that long, especially this time of the year. Sitting for a long period of time the fuel can gel and if the tank was not full while sitting, condensation can occur inside the tank. I would try a couple of cans of Heet or some other gas drier and then run the tank down as far as possible. When near empty, refill it with fresh fuel. If the problem still persits, then I would try a good brand of fuel injector cleaner, like Chevron with Techron. Stale fuel sitting for so long may have gummed up an injector or 2.

The vacuum leak mentioned by Toysrme above also sounds like a good possibility.

You seem to have covered all the ingition system parts already.

Also, don't forget to pull the codes from the ECU. This may point you in the right direction.

^^^ After this, change the fuel filter too....

hate to revive old threads but for the public good I found the issue.

After a conversation with Toysrme I went looking at the cold start injector to make sure he was doing alright, and found out that I was leaking gas out of #3 and #5 fuel injectors. My o-rings and grommets had gotten old and worn out in the course of 180 thousand miles..

so, a trip to the dealership later and I have new o-rings, grommets, and manifold insulators. I replaced them all for all 6 injectors because the ones on were so hard I felt that I was saving doing it again, they were about $3 for each piece, for a total of $78 dollars.

Anyway.. I think this has solved one of last remaining problems with my camry, next is fixing my busted endlinks. Thanks for those who replied.

Ouch, that's about the 4th ES / Camry in the last month with leaking injectors, caused by worn out o-rings I've run across!


Really glad you got it fixed tho! having a poorly running car is the pitts, but when you don't know what's causing it, wow. Always the worst!

I had to redo this today, #3 tore the o-ring as I put the rail on, evidently. Glad there were some descent rings from the front bank left over.. Now it's running pretty well and no leaky gas on my intake manifold to burn away. Though, it still putts a little at idle.
