Lotus Elise stumbling engine

LOTUS:

Lots Of Trouble, Usually Serious

[joshcop69]

I would've guessed water in the fuel, OR, more importantly, a little-known option: the No Revs Over 6 Grand If The Moron Driver Is Holding A Camera feature. A no-cost option, considering that if you take the vehicle to an authorized service facility, they will have a factory-trained technician drive the car, and duplicate the problem, if it's as OBVIOUS as the stumbling shown here.

it's only because the temp is lesse than 85°

[danap1981]

not seen one do that before.

[n238sh]

looks like the car was not up to operating temp and you are hitting the 5800 rmp throttle cutout.

[mikebarrdds]

Nope. It was at normal operating temp. Go back further in the comments. It was the wire harness. Had to be replaced under warranty.

get rid of that toyota motor and put in a k20a

[kumor768]

that would be a huge downgrade to a vtec! :p

[evand1581]

it is your cam position and knock sensor had same problem with my car where in each gear let you reach only to a certain rpm and it wont let you go any further no matter how much throttle

[lucarex50]

that problem?

[Gr0m3t]

ehhhh... throttle position sensor? or cams/crank sensor? maybe the maf sensor but it looks to me like the TPS is reading wrong through the rev so it has no idea where the throttle is

[viktord1]

it's a toyota engine. it shouldn't cost an arm to fix

[lovesthebass]

@viktord1 Actually Toyota parts are some of the most costly. I guess it's because they are probably the most reliable car parts.

[viktord1]

@lovesthebass

No way man! Compared to cars like BMW, audi, etc toyota parts are waaaaaaay cheaper. Even honda parts are considerably more expensive. (from my experience anyway) cheers

[cvaxle]

hey, question. I have a 1995 acura integra ls, and its misfiring only after the engine has warmed up and i give her over 1/4 throttle. she idles fine.Ive allready changed the spark plugs, spark plug wires, distributor cap, rotor, coil, and fuel filter. any ideas on what could be causing a misfire?

[thatdude2212]

i think its just your timing man.

knock's what usually causes it.

[pludder]

Sounds/seems like a faulty TPS.

[Dillon1108]

sounds like your low on gas

[midgetmayo]

that wouldv'e been my guess

[zpkpk]

you have it bad, i've got it to a certain degree on my camry lol, mine is just due to the spark leads as 1 of the seals have begun leaking gettin oil in the leads

[volvoc70r]

yeah we had a similar thing happen a fews months ago at my lotus dealership

[4G63PWR]

My brother has the same problem. Check my videos to see. Has it happend to you before? It feels like the throttle is open and closed really fast causing a jerk.

[dan2e2]

Guessed you've checked the obvious?

Spark Plugs/Leads

Coil Pack

Throttle Cable

[mikebarrdds]

It was the "harness." They had to replace the ENTIRE electrical "harness" under warranty, fortunately.

[konansk]

why is it doing that??? :S
