JStamberg Posted October 16, 2007 Share Posted October 16, 2007 Howdy folks, I haven't posted this question on any Toyota forums yet... I trust you guys and I'm curious to see what ideas you might have first. My dad's car: 1998 Toyota Camry LE (4 cyl, auto trans), 122,000 miles. He recently purchased it from a co-worker. My mom is the primary one who drives it, but only uses it a few times a week, for pretty short distances. While visiting my parents in Iowa my wife and I drove this car, and discovered it has a goofy lurch. Typical situation: Sitting at a stop light/sign, push on accelerator, then the car hesitates and lurches. This doesn't happen every time, but it is often enough (maybe 25% or more of the time) that it is a concern. It only happens from a stop (i.e. at very low speeds). The engine has actually quit on a couple of these situations. I've changed the plugs and wires, and I have a new fuel filter, but I have not installed it yet. Any other ideas of things to check? Thanks! Quote Link to comment Share on other sites More sharing options...
Hondasucks Posted October 17, 2007 Share Posted October 17, 2007 Clean the MAF and make sure you don't have any cracked vacuum lines. Does it burn oil? The 5SFE is known for sludging if the oil's not changed regulary, but Toyota will replace the engine for free if it's bad enough (Most of 'em just get a new head though).

4x4_Welder Posted October 17, 2007 Share Posted October 17, 2007 Check the fuel pressure, and check the TPS with an analog voltmeter. If the needle is anything other than smooth and steady as the throttle is opened, replace the TPS. If the pump is on it's way out with reduced fuel pressure, you can get similar results. Another thing is the air bypass solenoid/idle air controller. If this is gummed up, it can cause similar issues as well. Dumb question, but is there a CEL, any codes, or other issues like low idle, poor mileage, etc? Quote Link to comment Share on other sites More sharing options...

Dumb question, but is there a CEL, any codes, or other issues like low idle, poor mileage, etc? No codes, the idle seems normal. The mileage seems a little low (if I remember right, it was 24, mostly highway). Thanks for the tips guys, that'll keep me busy for a while.

Hondasucks Posted October 19, 2007 Share Posted October 19, 2007 24-26 is average for a V6 from what I've heard, four bangers get closer to 30 if not 30, depends on 5 speed vs. auto and if it's a wagon or not... But not sure cuz I've never owned a Camry that I drove :-P (The new ones are rated at 26 city 32 highway, 2.4L I-4 automatic) Quote Link to comment Share on other sites More sharing options...
JStamberg Posted November 5, 2007 Author Share Posted November 5, 2007 The rest of the story: While trying to replace the fuel filter, the lower fitting got jammed. I didn't have the time or tools to fix it right, so my dad brought it back into the shop. They fixed the fuel filter, and they had major problems with the lurching, etc. They did some snooping around, and, if I understood them correctly, one of the plugs into the ECU was partially disconnected. It drives fine now, and they charged us a very reasonable amount of labor for the whole repair... so I have no reason to second-guess the validity. Who would have guessed?
