Manifold-valve question

[historykeeper]

My 1987 Camry sputters at stoplights, etc. I believe it has to do with the manifold-exhaust valves. Does the entire motor have to be taken apart to access the problem?

Not sure what are manifold exhaust valves is on this car. Cylinder head valves, exhaust gas recycle valve?

Can you give more info if you want a good answer? To give a quick answer to your quick question, clean the idle air control valve first before trying anything else.

You say it sputters at stoplights, i think you are saying it wont idle right sometimes/intermittently? if this is the only symptom, i'd also suspect dirty fuel injectors or a fuel filter that needs replacing -

Thank you for your suggestion. I will buy a fuel filter. If it turns out that I need a fuel injector change, will I need all four? And can I, an 60ish lady, replace them myself?
