I hear that Cheryl...and if it was my vehicle it would have been cut already...it's my nephew's...so I'm being more cautious I guess..I'm hoping to get to the crank sensor this week....I also know that whatever I do , regardless of the amazing sources of knowledge here, will be scrutinized by a local mechanic if it needs to be handed off...and I have zero problem with paying a professional ..just trying to avoid him being told....you needed a computer...oh and also a crank sensor or other sensor... etc
