Mis-Fire under load ????

1996 Toyota Tacoma 2.4L 4CYL with 248,000

I have been having this issue for a while now... Under load at higher RPM's (most of the time accelerating onto interstate above 55 mph) I have an occasional misfire. Sometimes it's several misfires with in a few seconds of each other...other times it's just one and done like... I did notice a crack in my exhaust manifolds...could this be causing any issues?? Can I repair OR should I replace?? OEM or aftermarket??

During the hottest of summer days after town/city driving with quick stops. If I turn off the motor it is very hard to start compared to cold starts or all winter starting

Just replaced:
New plugs (denso) wires
New distributor cap
New fuel pump
New air filter

 

did you read any codes? that will help isolate the problem.

 

No codes...

 

Well an update for those of you that are interested... I went on eBay and purchased a new Coil and replaced about a week ago.

Not the first skip/miss yet!!! Coil must have been going bad. Problem gone!

Thanks for those read the thread!

 

Thanx for posting the solution, not everyone does that.
I would have suspected an injector.
