Question about 1999 Toyota Camry Solara

99 toyota check eng.lt on code po300,po303,po305,po171,p0420

I added injector cleaner to try to clean the injectors and next step would be to put new wires and plugs in any other ideas before I go to the dealer
thanx
Dan
i have the same problem, but mine is reading misfire on cylinder 5 and a code for random cylinder misfires, plugs are relatively new. should i just replace all coils and wires and go from there? except my year is 98

Hey Dan, It cannot hurt to change the Plugs and wires. Make sure and Check all the Fuses and Relays also. Sometimes the Realays can blow or just get old and send a Code also.

    Sorry Man! Yes, Just take the Plugs out and Inspect them for Cracks and Carbon Buildup or Unusual Wear. Like the Diode is only worn on 1 Side. Rate this Response for me Please! I am tryin to get back up in the Ranks!

    Thanks Bro! There really is no way to check the Wires Safely. Just use your best Judgement. No on the Plugs, Just clean them up and reinstall if they look ok.

I have several codes in my 99 Chevy S-10, po171, po174, po303, p1509. could there bo a common problem/


They are related mostly. All have to do with air intake. 170 codes are both sides running lean, to much air. 303 is a #3 misfire, could be a vacuum leak around the plenum. you replaced the spider. Could be the injector not seated right(smell for gas in the oil/dipstick), also could be a bad wire or spark plug. 1509 is an electrical problem with the idle air control motor. Check the plug for corrosion. Also wires usually break a round the plug. This also could be the problems with too much air.

If a tune up (spark plugs, ignition wires, distributor cap/rotor button or coil packs) don't work, try checking the fuel system.

We can't help you here

You need the car diagnosed

I doubt you have lifters,should have
OHC valve train

Most likely the oil passages are clogged up
in the cams with sludge

That's what happens when the wrong oil
& too long between changes takes place

You ruin the engine

99 toyota check eng.lt on code po300,po303,po305,po171,p0420


First Dan these car s are very sensitive, you don't ned to go to the dealer go to you local auto-zone and have dem check the light its free. I could be a number of things but just for starters if you have more than 60,000 miles, it could mean you need oxygen sensor but don't guess have it checked and get back to me I will be more than glad to help. Good Luck. hey and leave me a rating.. thanks

Still need the codes.
Injectors can go "bad" in a couple of different ways; all they are is an electromagneticaly controlled nozzle. When the ECU "fires" the injector, it pulses a ground circuit for 4-8 milliseconds, the electromagnet powers up, the valve at the bottom of the injector opens, and the fuel shoots out, under pressure. The wire can be bad/chafed/corodded/ The electromagnet may be weak. The nozzle may be stuck. Lots of things. But, to put in an injector for a number 4 cylinder misfire (p-0304 code) would be one of the last things that I would do.
