idle surging problems
hey guys...i searched the faq for idle problems...but every1 seems to say either tps or vacuum problem....heres my problem....after i installed aftermarket injectors in my 87 t2, it will continuously surge between 1000 and 1500 rpm constantly cold or fully warm...wen i first start it up..its fine...driving is fine too....when i start it up, after the rpm goes down frum the rapid warm up, it will begin to surge...i took apart my uim multiple times to check for vacuum leaks and used brakleen and throttle body cleaner...could not find any leaks....if sum1 can give me an ez way to adj. the tps if thats the problem or if u know wuts going on at all lemme know...

ok crap...a coolant leak sprung out frum under my intake manifold and i had to remove the uim to get to it again...and now...my car surges again...all hoses are hooked up...so i have no leaks...tried to adjust the tps again...and it just doesnt work...everytime i step on the throttle after adjusting the tps to 1k ohm, it will return to 1.5k ohm after stepping on the pedal...any clues on how to cure this?...i looked up a new tps thru mazdatrix and their asking $230....im not willing to pay that....if u guys have any info thx!
