93 legacy stall after hard acceleration

[grimaceNMike]

This morning I got into a drag race with a Jeep, this race has been weeks in the making.. The jeep driver uses the bus lane to cut in front of the line.

We never went over 40mph but it was more a 0-40 race from an intersection. I don't push my car hard and today I felt it necessary to beat this guy. I've not seen my tachometer reach 5000 rpms because I have an automatic and the car shifts when it wants to, but today it revved all the way up to 5500 rpms while in 2nd gear. As soon as I took my foot off the accelerator the engine stalled out at 40mph. All my dash lights came on and I pulled to the side of the road. Once pulled over I restarted the engine and it hiccupped and died. Tried again, it ran rough for a few moments and now is running fine again.

My question is: what did I do to my car? Lol. why did it stall after being pushed hard?

New fuel pump within the last 10 months and a full fuel tank.

 

Thanks! Mike

I would have said it may have slipped timing, but, you sure it's running as well as before?

 

hmmm, maybe a dirty IACV or gummy throttle body?

 

 

interesting.

I wish I had a follow up answer, but I do not. I have not experienced anything like that since, but I have not pushed it hard like that since then either. A few months before this I had an issue with my MAF sensor, while trying to diagnose the issue I ended up cleaning the IACV and replacing the EGR valve.

Over worked coil pack?? It’s be an odd scenario though if that were the case. 

If your engine doesn’t do that sort of hard pull or those sorts of revs it’ll have issues doingnit out of the blue. I’d have a go at holding the gear and revving the engine out to this point then manually changing the gear into 3rd or drive. No need for WOT to do this. 

^ This practise comes from a member on another forum who reckons if it’s a grandma driven car, you need to “train” it to be more lively by doing things gently as you would if you were training from slob to athelete. 

Yes things won’t magically repair overnight, but going gently harder over time will allow suspension bushes to free up and become more elastic - go like the clappers straight up and you could split a bush or three.

It could be the same for an engine and box too, although I’ve never experienced that before. 

I’d definitely check your timing belt to make sure it’s stull aligned properly - and check for any stored codes too.

i had an experience similar to this once.. got on it to get through a traffic light that was changing... engine died.. coast to a reasonably safe spot to stop (thankfully it was a downhill run, as places to stop are few & far between at that location)..  Mine did not restart however.. had to be trailered home and the timing redone.

definitely check your timing belt. it can be off a tooth or two and still run
