6G Celicas Forums

Hi guys, im new to this forum and im kinda desperate. i have a 1995 Toyota Celica ST 7afe 5 speed with 219xxx miles.. my car has recently been misfiring randomly. i get no CEL. it will just idle fine one second misfire for a second and recover. its very sluggish. i lost about 75mpg per tank. and it jerks on accelleration.. im just looking to see if anyone else has had the same problem. i seem to think it is my distributor. i pulled the #1 wire from the distributer and watched the spark and it doesnt spark constantly. i also seem to think it could be my valve seal leaking oil on the spark plug causing it to miss. my valve seals have been going. if i let my car sit for a few days and start it up it smokes some. its been that way since ive bought the car but it never misfired. im about to make a video of it tonight. my budgets tight and im just trying to make sure that's what i need to replace so any help is appreciated. thanks, jake.

Generally the distributor will throw code 12? if I recall correctly when it starts to give issues. If it was the distributor or the coil you'd have a general misfire, though if one of the contacts on the cap is burnt that'd be the exception. It could be you need new plugs if they haven't been changed in awhile, also go with something like the NGK G-power platinum as platinum is more resistant to fouling. The 7A-FE is notorious for burning oil from stuck oil control rings as it is, so compounding the issue with leaking valve stem seals could just be too much for it to burn off. Though you should be having to top off oil every 500-1,000 or so miles if it's that bad.

when was the last time you gave the car a tune up? try changing the cap and rotor.

I had the same problem with mine last summer. One of my plug wires was chewed up so a tune up solved that problem!

Thanks for the advice. my car recently has started missing almost constanly now, it started out as weak miss but its gotten worse. and its still not throwing a code. i drive it nearly 70-100 miles daily. Yes it does burn some oil i find myself adding about a quart every 2 weeks to a month. i plan on changing the distributor, Upgrade to NGK G- power plugs, and get new wires. hopefully that will take car of the miss. i plan on replacing my head-gasket, valve seals and piston rings down the road but i don't have the time for that right now. like i said anymore help would be greatly appreciated.

here are a few videos -

and for this video if i am correct (which idk if it is..) if it was a bad spark plug, when i pull a spark plug wire when its running 1 of the 4 cylinders wouldnt make a difference. and in this video when i pull each plug wire the car misses. does this mean it could be the valve seal? and if so should i go with hotter plugs to burn off the access?
