at idle my revs have a mind of their own!

up and down up and down,my revs jump from 500 to 1200 rpm and just keep going up and down!tonight it started and cut out 2 secs later

my car is a 93 auto

ive just removed my aiv's and put in new intercoolers.

also it has an occasional hesitation at about 50 -80 mph?

any ideas guys plz

thanks jason

Jay,

dunno if you've already checked the 'usual suspects'- temp sensor and TPS. Probably either (or both!) of these little f**kers!!!

hey bud,those sensors seem ok but id best replace em anyway,thanks m8

did u sort ya wheels

sorry m8 but ya not gonna want mine

i forgot all about calling ya,sorry bud

Jay, are you gonna bring this god damn car round to me or what??? Don't replace a sensor *just* because they are known to go wrong - a new one is just as likely to go wrong really.... The idle is simple to sort - only requires some carb cleaner in the right places

 

CheerZ,

hey bud,im coming down tommorow.ill call ya in the mroning if thats ok.jay

I dunno. I had a stall problem on my 90NA, and the idle used to jump all around the place, occasionally stalling out (especially after freeway driving). I just cleaned the hell out of my throttle bodies and the engine now runs over 1500 all the time... it never stalls anymore, though.
