I Have a 1990 Toyota 4 runner that runs really good just replaced spark plugs on it they where fouled out it has been rough to start when I changed the plugs this hard starting went away. Now I start the car with no-problems my problem is that after the car has been running for like 5 to 7 mins after it starts to get warm the engine idle jumps from 12oo rpms to to 23oo rpms and back to 1200 and it keeps doing that untill I put the car in gear then it runs fine but if I put the car in nuetral or park idle gets irregular again any suggestions?
