My 97 Toyota Tercel keeps burning out spark plugs
First noticed last year after long drive of 300 miles straight. Burnt out one spark plug and car bucked like a pony running on 3. Had one coil replaced and changed the spark plugs. Fixed. Now 1 year later, I burn out a plug every month or so after a long drive, or one uphill. I feel like it has something to do with the amount of fuel the plugs are getting. It is stick shift and when the timing between the brake and the clutch is difficult, like going up a steap incline in snow or driving in real racing traffic in NYC then the spark plug burns out (ends burn then break off) under the coil packs only. ***This car has on the engine a sticker requesting only double grounded spark plugs (two arms at end) which I noticed a few months back. The double plug gives the car a lot more power but is burning out quite quickly. Car has 96K. Problems started at 70K. Should I try the new Bosch 4 grounded plug? If it is a fuel mixture problem, how does one adjust the amount of fuel going to the plugs? Thanks |
